(a)
To find the range of data.
(a)
Answer to Problem 15E
Range=
Explanation of Solution
Given information: Box-and-whisker plot.
Formula Used:Range of the data=
Calculation:
As the range of the data:
So,
Range=
Hence,
Range=
(b)
To describe the distribution of data.
(b)
Answer to Problem 15E
Positively Skewed
Explanation of Solution
Given information: Box-and-whisker plot.
Calculation:
The distribution is positively skewed as the mean typically gets pulled toward the tail, and is greater than the median.
(c)
To find the interquartile range of data.
(c)
Answer to Problem 15E
Interquartile Range=
Explanation of Solution
Given information: Box-and-whisker plot.
Formula Used:Interquartile range of the data=
Calculation:
As the Interquartile range of the data =
So,
Interquartile Range=
Hence,
Interquartile Range=
(D)
To describe the data more spread out.
(D)
Answer to Problem 15E
Yes
Explanation of Solution
Given information: Box-and-whisker plot.
Calculation:
Yes, the data is more spread out.
Because range of the data is much greater than interquartile range.

- Reconsider the patient satisfaction data in Table 1. Fit a multiple regression model using both patient age and severity as the regressors. (a) Test for significance of regression. (b) Test for the individual contribution of the two regressors. Are both regressor variables needed in the model? (c) Has adding severity to the model improved the quality of the model fit? Explain your answer.arrow_forwardThe output voltage of a power supply is assumed to be normally distributed. Sixteen observations taken at random on voltage are as follows: 10.35, 9.30, 10.00, 9.96, 11.65, 12.00, 11.25, 9.58, 11.54, 9.95, 10.28, 8.37, 10.44, 9.25, 9.38, and 10.85. (a) Test the hypothesis that the mean voltage equals 12 V against a two-sided alternative using a = 0.05. (b) Construct a 95% two-sided confidence interval on μ. (c) Test the hypothesis that σ² = 11 using α = 0.05. (d) Construct a 95% two-sided confidence interval on σ. (e) Construct a 95% upper confidence interval on σ. (f) Does the assumption of normality seem reasonable for the output voltage?arrow_forwardAnalyze the residuals from the regression model on the patient satisfaction data from Exercise 3.

In addition to satisfaction, data were collected on patient age and an index that measured the severity of illness. (a) Fit a linear regression model relating satisfaction to patient age. (b) Test for significance of regression. (c) What portion of the total variability is accounted for by the regressor variable age?
