Prompt A department store is running a promotion where it gives every customer a special scratch-off ticket. The manager of the store claims that 25% of the tickets offer a $10 voucher. However, a customer questions this claim as out of 70 customers who have received a scratch-off ticket, only 15 have received the $10 voucher. Assume it reasonable to assume that the 70 tickets are a random sample of all the tickets the department store gives out. At the significance level a = 0.05, does the sample support the customer's belief that the proportion of tickets with a $10 voucher is less than 25%?** a. State a correct pair of hypotheses. b. Identify a correct test (by name or by formula) and check appropriate conditions. c. Calculate the appropriate test statistic and p-value. d. State a correct conclusion in the context of the study, using the result of the statistical test.

Fire departments in your county have an average benchmark of 6 minutes on a fire call from the time the 911 operator takes the call to the time the first firefighter arrives on the scene. This 6-minute average includes a 1-minute call handling time from when 911 gets the call to when they notify the fire department. There is a 1-minute time from when the firefighters are notified to when they get out of the fire station. Then they have 4 minutes from when they leave the station to when they arrive on scene. Two fire departments in your county are being compared. From one fire department, a random sample of 10 calls has a mean of 6.51 minutes total with a standard deviation of 0.26 minutes. From the other fire department, a random sample of 11 calls shows a mean of 6.42 minutes with a standard deviation of 0.19. Construct a 90% confidence interval for the difference in the mean call time between the two fire departments. Fire departments in your county have an average benchmark of 6…
