The expected count for the cell corresponding to east coast subscribers who responded "yes" is 19.2.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

We need to first calculate the expected frequencies for each cell under the assumption that the null hypothesis of homogeneity is true.

The null hypothesis of homogeneity assumes that the proportion of internet subscribers satisfied with their internet speeds is the same on both the east and west coasts of the United States.

To calculate the expected frequencies, we can use the formula:

Expected frequency = (row total x column total) / grand total

For the cell corresponding to east coast subscribers who responded "yes":

Expected frequency = (row total for east coast x column total for "yes") / grand total

= (80 x 48) / 200

= 19.2

Therefore, the expected count for the cell corresponding to east coast subscribers who responded "yes" is 19.2.

Step-by-step explanation:

The forecasted sales in August 2021, using exponential smoothing with a smoothing constant of 0.31, is approximately 52.3251 units.

Exponential smoothing is a forecasting method that assigns weights to historical data points, giving more importance to recent observations. The forecasted value for a specific period is calculated by combining the actual value for that period with the forecasted value for the previous period. The formula for exponential smoothing is:

Ft = α * At-1 + (1 - α) * Ft-1

Where Ft is the forecasted value for period t, At-1 is the actual value for the previous period, Ft-1 is the forecasted value for the previous period, and α is the smoothing constant.

Given that the forecast in April 2021 was 39 units and the monthly sales data from April to September 2021 are 48, 55, 46, 54, 53, and 52 units, we can calculate the forecasted sales for each subsequent month using the exponential smoothing formula.

Using the given values and the formula, we can calculate the forecasted sales for August 2021 as follows:

Ft = 0.31 * 52 + (1 - 0.31) * 52.3251 = 52.3251

Therefore, the forecasted sales in August 2021, rounded to at least 4 decimals, is approximately 52.3251 units.

The Diwali occurred on 0.408 or 40.8% of the year in 2017.

To find the fraction of the year that Diwali occurred in 2017, we need to divide the number of days between Diwali and the start of the year by the total number of days in the year.

Diwali occurred on Thursday, October 19, 2017. The start of the year 2017 is January 1, 2017 which is a Sunday.

There are 365 days in a non-leap year. Since 2017 is not a leap year, there are 365 days in that year.

So the fraction of the year that Diwali occurred in 2017 can be calculated as: (days between Diwali and the start of the year) / (total days in the year) = ( 19 + 31 + 30 + 31 + 30 + 19 ) / 365 = (148) / 365 = 0.408

So, the Diwali occurred on 0.408 or 40.8% of the year in 2017.

Therefore, Diwali occurred on 0.408 or 40.8%

Step-by-step explanation:

To find the area of the parallelogram, we just need to multiply the base and height

7 x 17 = 119

Assuming the shape of the car is rectangular, we do the same: base x height

5 x 14 = 70

Now, we just subtract 70 from 119

119 - 70 = 49

The equation represented by Ms. Wilson's model is n² + 13n + 40 = (n + 8)(n + 5)

The partially completed model is given as:

    |  n

    |  n²

The inequality sign is not correct because the > symbol means greater than. However, up to and including $90 can be spent so the inequality sign should be ≥ (greater than or equal to).

The best description of the error in the student's inequality is; The inequality symbol should be Greater-than-or-equal-to instead of > since up to and including $90 may be spent.

We are told that;

The solution set of the system of equations y = -x + 1 and y = x² + 5x + 6 includes the ordered pairs (-1, 2) and (-5, 6).

To find the ordered pair that is in the solution set of the system of equations y = -x + 1 and y = x² + 5x + 6, we need to solve the equations simultaneously.
First, let's set the two equations equal to each other:
-x + 1 = x² + 5x + 6
Rearranging the equation, we have:
x² + 6x + 5 = 0
Next, we can factor the quadratic equation:
(x + 1)(x + 5) = 0
Setting each factor equal to zero, we find two possible values for x:
x + 1 = 0

-->  x = -1
x + 5 = 0  

-->  x = -5
Now that we have the possible values for x, we can substitute them back into either of the original equations to find the corresponding y-values.
For x = -1:
y = -(-1) + 1

= 2
So, the ordered pair (-1, 2) is in the solution set.
For x = -5:
y = -(-5) + 1

= 6
In conclusion, The ordered pair (-5, 6) is also in the solution set.

The radius of convergence,R, of the series \(\[ \sum_{n=1}^{\infty} ~9(-1)^n~ nx^n \]\) is (1, ∞)

We know that for a power series ∑an (x - p)^n

if |x - p| < R then the series converges,

and if |x - p| > R then the series diverges.

Here, the number R is called the radius of convergence.

We have been given a series \(\[ \sum_{n=1}^{\infty} ~9(-1)^n~ nx^n \]\)

We need find the radius of convergence.

We use ratio test.

We know for \($\lim_{x\to\infty}~ | \frac{a_{n+1}}{a_n}|=L\)

if L < 1, then the series converges

and If \($\lim_{x\to\infty}~a_n \neq 0\) then \(\sum a_n\) diverges.

Using ratio test for given series,

\($\lim_{x\to\infty}~ | \frac{9(-1)^{n+1}~ (n+1)x^{n+1}}{9(-1)^n~ nx^n}|\\\\\\\)

= \($\lim_{x\to\infty}~ | \frac{(n+1)x^{n+1}}{nx^n}|\)

= \($\lim_{x\to\infty}~ | \frac{(n+1)x}{n}|\)

\(=|x| $\lim_{x\to\infty}~ | \frac{n+1}{n}|\)

= |x|

This means, the series is convergent for |x| < 1.

The t-percentile defines the boundaries of the confidence interval and is equal to the critical value of t with a positive or negative sign, depending on whether the confidence interval is one-sided or two-sided.

A t-distribution table determines the t-percentile required to construct two-sided confidence intervals. The first step in determining the t-percentile is to know the degrees of freedom and confidence level. The next step is to find the critical value of t from a t-distribution table. The t-distribution table lists values for the probability density function, cumulative distribution function, and percentile points of the t-distribution.

The table is arranged in rows and columns, with the rows corresponding to the degrees of freedom and the columns corresponding to the significance level. The critical value of t is the value that separates the central area of the t-distribution from the tails of the distribution. It is used to define the boundaries of the confidence interval. The t-value is the same as the critical value of t, but it has a positive or negative sign depending on whether the confidence interval is one-sided or two-sided. The t-percentile that is required to construct two-sided confidence intervals is given by the following steps:

Step 1: To determine the t-percentile, the degrees of freedom and confidence level are needed.

Step 2: Find the critical value of t from a t-distribution table.

(a) 95% confidence level, 15 degrees of freedom.

Using the T-Distribution Calculator with degrees of freedom (df) = 15, a 95% confidence level, the value of t is found to be 2.1318. Therefore, to construct the confidence interval, the t-value is ± 2.1318.

(b) 95% confidence level, 24 degrees of freedom.

Using the T-Distribution Calculator with degrees of freedom (df) = 24, a 95% confidence level, the value of t is 2.064. Therefore, to construct the confidence interval, the t-value is ± 2.064.

(c) 99% confidence level, 13 degrees of freedom.

Using the T-Distribution Calculator with degrees of freedom (df) = 13, a 99% confidence level, the value of t is 3.012. Therefore, to construct the confidence interval, the t-value is ± 3.012.

(d) 99.9% confidence level, 15 degrees of freedom.

Using the T-Distribution Calculator with degrees of freedom (df) = 15, a 99.9% confidence level, the value of t is found to be 3.579. Therefore, to construct the confidence interval, the t-value is ± 3.579.

The t-percentile can be found using a t-distribution table, which lists the critical value of t for different degrees of freedom and significance levels. The t-percentile defines the boundaries of the confidence interval and is equal to the critical value of t with a positive or negative sign, depending on whether the confidence interval is one-sided or two-sided.
