A random sample of size 36 is taken from a normal population with a mean of 50 and a standard deviation of 5. What is the sample standard deviation?
Answers
The sample standard deviation is approximately 0.83.
Sample size \(($n$)\) = 36
Population mean \(($\mu$)\) = 50
Population standard deviation \(($\sigma$)\) = 5
The sample standard deviation, denoted as \($s$\) can be estimated using the formula:
\(\[ s = \sqrt{\frac{\sum_{i=1}^{n}(x_i - \bar{x})^2}{n-1}} \]\)
where:
\($x_i$\) represents the individual data points in the sample
\($\bar{x}$\) is the sample mean
In this case, since we don't have individual data points, we can use the population standard deviation as an estimate for the sample standard deviation when the sample size is relatively large (as in this case \($n = 36$\)). This approximation is known as the standard error of the mean.
Therefore, the sample standard deviation can be approximated as:
\(\[ s \approx \frac{\sigma}{\sqrt{n}} \]\)
Substituting the given values:
\(\[ s \approx \frac{5}{\sqrt{36}} = \frac{5}{6} \] = 0.83\)
Hence, the sample standard deviation is approximately 0.83.

Your company requires its employees to work between 10 a.m. and 3 p.m. each day, but employees can decide whether they will work their additional hours before or after this time period. What is this arrangement called in your textbook
Answers
In the textbook, this arrangement is referred to as "flextime" or "flexible working hours."
Flextime is a work arrangement that allows employees to have control over their work schedule within certain core hours. In this case, the core hours are between 10 a.m. and 3 p.m., during which all employees are required to be present at work. However, employees have the flexibility to choose their additional working hours either before or after the core hours.
Flextime offers employees the freedom to adjust their work schedule to accommodate personal obligations, preferences, or other commitments outside of work. It recognizes that individuals have different peak productivity hours and work-life balance needs. By allowing employees to choose their additional working hours, it promotes autonomy and can contribute to increased job satisfaction and work-life integration.

Solve ln (3x + 7) = 1. Round to the nearest thousandth.
A. 0. 385
B. 3. 239
C. 9. 718
D. −1. 427
Answers
The solution to the equation ln(3x + 7) = 1, rounded to the nearest thousandth, is x ≈ 0.385 (option A).
To solve the equation ln(3x + 7) = 1, we can use the properties of logarithms. The natural logarithm ln(y) is the inverse function of the exponential function \(e^y\). In this case, we have ln(3x + 7) = 1, which means \(e^1\)= 3x + 7.
We can rewrite the equation as e = 3x + 7 and solve for x. Subtracting 7 from both sides gives e - 7 = 3x. Dividing both sides by 3, we have (e - 7) / 3 = x.
To round to the nearest thousandth, we substitute e = 2.718 (approximately), which is the base of the natural logarithm. Plugging this value into the equation, we get (2.718 - 7) / 3 ≈ -1.427.
However, the options provided do not include a negative value. Therefore, we consider the positive solution by taking the absolute value, giving x ≈ 1.427. Rounding this value to the nearest thousandth, we obtain x ≈ 0.385, which corresponds to option A.

a. Explain why (3, 6) is on this line.
b. Explain why (0, 0) is not on this line.
Answers
Answer:
Step-by-step explanation:
If a line with a slope passes through a point with a value such as in this one, which is (1,3), then it must have a y-intercept and a slope. The y-intercept is when the x-value's value is 0 but the y-value is more than 0.
(3,6) is on the line as it corresponds with the slope.
(0,0) is not on this line as the y-value nor the x-value has a coordinate, which is a requirement to make it an ordered pair.

Find the median, first quartile, third quartile, and interquartile range of the data.
68, 74, 67, 72, 63, 70, 78, 64, 76
Answers
Given:
The data set is:
68, 74, 67, 72, 63, 70, 78, 64, 76
To find:
The median, first quartile, third quartile, and interquartile range of the data.
Solution:
We have,
68, 74, 67, 72, 63, 70, 78, 64, 76
Arrange the given data in ascending order.
63, 64, 67, 68, 70, 72, 74, 76, 78
Now divide the data in two equal parts.
(63, 64, 67, 68), 70, (72, 74, 76, 78)
So, the median of the given data set is 70.
Divide each parenthesis in two equal parts.
(63, 64), (67, 68), 70, (72, 74), (76, 78)
Now, the first quartile is:
\(Q_1=\dfrac{64+67}{2}\)
\(Q_1=\dfrac{131}{2}\)
\(Q_1=65.5\)
The third quartile is:
\(Q_3=\dfrac{74+76}{2}\)
\(Q_3=\dfrac{150}{2}\)
\(Q_3=75\)
The interquartile range (IQR) is the difference between third quartile and first quartile.
\(IQR=75-65.5\)
\(IQR=9.5\)
Therefore, median is 70, first quartile is 65.5, third quartile is 75 and the interquartile range is 9.5.

kelvin makes a map of his apartment using a coordinate system with yards as the units. the point (-9, 8) represents the main entrance of the apartment and the point (-5, 6) represents the location of the kitchen. approximately how far apart are the main entrance and the kitchen?
Answers
So, approximately, the main entrance and the kitchen are 4.47 yards apart by distance equation.
The distance formula is used to calculate the distance between two points in a coordinate plane. The formula is based on the Pythagorean theorem and involves finding the square root of the sum of the squares of the differences in the x-coordinates and the y-coordinates of the two points.
In this case, we are given two points: (-9, 8) and (-5, 6). To find the distance between these two points, we can plug the coordinates into the distance formula, which gives us:
distance = √[(x2 - x1)² + (y2 - y1)²]
where x1 and y1 are the coordinates of the first point and x2 and y2 are the coordinates of the second point.
Plugging in the given coordinates, we get:
distance = √[(-5 - (-9))² + (6 - 8)²]
which simplifies to:
distance = √[4² + (-2)²]
The square of 4 is 16, and the square of -2 is also 4 (since the negative sign is squared away), so we can simplify further:
distance = √[16 + 4]
distance = √[20]
Finally, we take the square root of 20 to get the distance:
distance ≈ 4.47 yards.

In calculating chi-square test statistics, we use the squared difference between the observed (O) and expected (E) values in each cell, divided by the expected value (E). This is referred to as the squared difference, denoted as option C.
The expected number of successes for the Rosi treatment group is given as 126.12, which corresponds to option C.
Regarding the statement, if the three treatments are not equally effective, to reject the null hypothesis, the chi-square statistic for this example will be larger. This statement is true. When the treatments are not equally effective, there will be larger differences between the observed and expected values, leading to a larger chi-square statistic. This increased statistic indicates a greater deviation from what would be expected under the null hypothesis, providing evidence to reject it.
In the given table for testing independence in 2-way tables, the observed values are presented alongside the expected values (in parentheses) for each category. The total counts for each row and column are also provided.

The meaning of the translation (x + 6, y + 10) is that all points in a coordinate plane are moved 6 units to the right and 10 units up.
In other words, for any point (x, y) in the original position, after the translation, the new coordinates would be (x + 6, y + 10). This means that the x-coordinate of each point is increased by 6 units, resulting in a shift to the right, and the y-coordinate is increased by 10 units, resulting in a shift upwards.
