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.
