7. A group of diners were asked how much they would pay for a meal. Their responses were: $7.50, $25.00, $10.00, $10.00, $7.50, $8.25, $9.00, $5.00, $15.00, $8.00, $7.25, $7.50, $8.00, $7.00. $12.00. a. find the standard deviation of this data. Explain what the mean and standard deviation tell you about how much the group of diners would pay for a meal. b. Calculate the five-number summary for this data. c. Calculate the range and IQR for this data. d. Create a boxplot for the data


8. Studies are often done by pharmaceutical companies to determine the effectiveness of a treatment. Suppose that a new cancer drug is currently under study. Of interest is the average length of time in months patients live once starting the treatment. Two researchers each follow a different set of 40 cancer patients throughout their treatment. The following data (in months) are collected. a. Find the standard deviation of each group. b. Calculate the 5-number summary for each group. c. Calculate the range and IQR for each group. d. Create side-by-side boxplots and compare and contrast the two groups.

to look at 36 weeks instead of 20 weeks. His quality improvement team provided him with the data below after an “intervention” was introduced in week 20. Calculate the upper and lower control limits and then construct a control chart. Display your chart. Question: Using the rules for detecting special causes, can you detect any special causes in this case? If so, what special causes can you detect? What does this mean? Was the intervention successful in reducing the delays?...
