The null hypothesis is rejected at a 5% significance level (α = 0.05) when the p-value is smaller than 0.05.

In statistical hypothesis testing, the null hypothesis is a statement that assumes no significant difference or relationship between variables. The p-value is a measure that quantifies the strength of evidence against the null hypothesis. It represents the probability of obtaining the observed data, or more extreme results, assuming the null hypothesis is true.

The significance level, typically denoted as α (alpha), is the threshold used to determine whether to reject the null hypothesis. The most common significance level is 0.05 or 5%. If the p-value calculated from the test is smaller than the significance level, it indicates that the observed data is unlikely to have occurred by chance alone, leading to the rejection of the null hypothesis.

For example, if we conduct a hypothesis test and obtain a p-value of 0.03, and we have set our significance level at 0.05, then since 0.03 < 0.05, we would reject the null hypothesis. This means that the observed data provides sufficient evidence to support an alternative hypothesis or claim.

The null hypothesis is rejected at a 5% significance level (α = 0.05) when the p-value is smaller than 0.05. This indicates that the observed data provides significant evidence against the null hypothesis and supports an alternative hypothesis or claim.

The number of oranges that are expected to weigh more than 4 oz is:

1400 - (1400 × 0.0228)≈ 1368.

The mean weight of the oranges growing in an orchard is 8 oz and standard deviation is 2 oz, the distribution of the weight of oranges can be represented as normal distribution.

From the batch of 1400 oranges, the number of oranges is expected to weigh more than 4 oz can be found using the formula for the Z-score of a given data point.

\(z = (x - μ) / σ\)

Wherez is the Z-score of the given data point x is the data point

μ is the mean weight of the oranges

σ is the standard deviation

Now, let's plug in the given values.

\(z = (4 - 8) / 2= -2\)

The area under the standard normal distribution curve to the left of a Z-score of -2 can be found using the standard normal distribution table. It is 0.0228. This means that 0.0228 of the oranges in the batch are expected to weigh less than 4 oz.

The value of θ in the fourth quadrant is approximately -53.13°, cos(θ) = -0.65, sin(θ) = -0.76, and tan(θ) = 1.18.

In standard position, the terminal side of an angle θ lies in the fourth quadrant if and only if the angle is between 180° and 270°. To find the angle, we can use the inverse tangent function.

First, we need to find the slope of the line, which can be found from the equation:

3x - 4y = 0

Rearranging the equation to y = mx + b form, where m is the slope and b is the y-intercept:

y = (4/3)x

Since the line lies in the fourth quadrant, the slope is negative. The tangent of an angle in the fourth quadrant is also negative, so we can find the angle by using the inverse tangent function:

θ = atan(-4/3) = atan(3/4)

The value of the angle θ in radians is approximately -0.93. To convert it to degrees, we multiply it by 180/π:

θ = -0.93 * 180/π = -53.13°

Next, we can find the cosine and sine of the angle using trigonometric functions:

cos(θ) = -cos(-53.13°) = -cos(53.13°) = -0.65

sin(θ) = sin(-53.13°) = -sin(53.13°) = -0.76

Finally, we can find the tangent of the angle:

tan(θ) = sin(θ) / cos(θ) = -0.76 / -0.65 = 1.18 (since both numerator and denominator are negative, the result is positive)

Therefore, the value of θ in the fourth quadrant is approximately -53.13°, cos(θ) = -0.65, sin(θ) = -0.76, and tan(θ) = 1.18.

The domain of f is the interval [-37, ∞).

For a function to have an inverse, it must be one-to-one, which means that it must pass the horizontal line test, i.e., each horizontal line should intersect the graph of the function at most once.

The derivative of the function is:

\(f'(x) = 6 + (1/2√(x+37))\)

f'(x) is always positive because 6 is positive and the square root is positive, so f(x) is an increasing function. This means that f(x) is one-to-one and therefore has an inverse.

To determine the largest interval on which f has an inverse, we need to find the domain of f. The square root can only take non-negative values, so we must have x+37 ≥ 0, which means x ≥ -37.

Therefore, the domain of f is the interval [-37, ∞).

Since f is increasing over this interval, its inverse will also be increasing, and the largest interval on which f has an inverse is [-37, ∞).

The proper question is "Let f(x)=6x+√(x+37)Choose the form of the largest interval on which f has an inverse and enter the value(s) of the endpoint(s) in the appropriate blanks. Then find (f−1)′(0)

Answer:

Answer is as follows

Step-by-step explanation:

a. The probability of choosing a blue marble can be found by dividing the number of blue marbles by the total number of marbles in the jar. So the probability of choosing a blue marble is:

P(blue) = 4/18 = 2/9

b. Similarly, the probability of choosing a green marble is:

P(green) = 4/18 = 2/9

c. There are no black marbles in the jar, so the probability of choosing a black marble is 0.

Answer:

Blue marbles: \(\frac{2}{9}\)

Green marble: \(\frac{2}{9}\)

Black marble: \(0\)

Step-by-step explanation:

It is given that a jar contains 4 blue, 4 green, 7 yellow, and 3 red marbles, for a total of 18 marbles in all. To solve for probability, you will put the part of what you are solving for (in this case, a certain color marble) over the whole (which includes all colors of the marble together).

a. What is the probability of choosing a blue marble?

It is given to us that there are 4 blue marbles total in the given jar. Therefore, the fraction of blue marbles/all marbles will be 4/18.

You may be asked to simplify. Simplify fractions by dividing common factors. The common factor in this case will be 2:

\(\frac{(\frac{4}{18})}{\frac{2}{2}} = {\frac{2}{9}\)

\(\frac{2}{9}\) is your probability for blue marbles.

b. What is the probability of choosing a green marble?

It is given to us that there are 4 green marbles total in the given jar. Therefore, the process will be the same as blue, meaning that your answer is 2/9 simplified:

\(\frac{\frac{4}{18}}{\frac{2}{2}} = \frac{2}{9}\)

\(\frac{2}{9}\) is your answer.

c. What is the probability of choosing a black marble?

There are no black marbles in the given set (the colors being blue, green, yellow, and red). Therefore, within the given set, there will be no chance of obtaining a black marble.

\(0\) is your answer.

To determine if equations are parallel, perpendicular, or neither, you need to examine the slopes of the lines represented by the equations.

The slope of a line is calculated using the formula m = (y2 - y1) / (x2 - x1). The slope-intercept equation y = mx + c can be used to identify the slope and y-intercept of a line, where m represents the slope, while c represents the y-intercept.

If two equations are parallel, they will have the same slope.

If two equations are perpendicular, then the product of the two slopes should equal -1. This also means that if one slope is m, the other must be -1/m. If the slope of one line is zero, the line is horizontal, and any line perpendicular to it has a slope of undefined.

Standard Deviation = 98.21

First Quartile (Q1) = 12

Median = 48

Third Quartile (Q3) = 70

65th Percentile = 50

​

To find the mean, variation, standard deviation, quartiles, median, and percentile for the given data set, we can follow these steps:

Step 1: Sort the data in ascending order: 8, 12, 30, 35, 48, 50, 62, 70, 78.

Step 2: Calculate the mean:

\(Mean = \frac{8 + 12 + 30 + 35 + 48 + 50 + 62 + 70 + 78}{9} = 43.33\) (rounded to two decimal places).

Step 3: Calculate the variation:

\(\text{Variation} = \frac{{\sum((x_i - \text{mean})^2)}}{n}\\\\= \frac{{((8 - 43.33)^2 + (12 - 43.33)^2 + \ldots + (78 - 43.33)^2)}}{9}\\\\= 9646.22 \quad\)
