G Test 4 E Question 13 of 25 (1 point) | Question Attempt: 1 of 1 Time Remaining: 3:35:45 0 Siena V 13 14 15 16 17 18 19 20 21 22 23 24 Espanol For a study conducted by the research department of a pharmaceutical company, 245 randomly selected individuals were asked to report the amount of money they spend annually on prescription allergy relief medication. The sample mean was found to be $17.60 with a standard deviation of $5.30. A random sample of 275 Individuals was selected independently of the first sample. These individuals reported their annual spending on non-prescription allergy relief medication. The mean of the second sample was found to be $ 18-40 with a standard deviation of $ 40. As the sample sizes were quite large, it was assumed that the respective population standard deviations of the spending for prescription and non-prescription allergy relief medication could be estimated as the respective sample standard deviation values given above. Construct a 93 20 confidence interval for the difference Hi -Hy between the mean spending on prescription allergy relief medication (Hj ) and the mean spending on non-prescription allergy relief medication (H2). Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to at least two decimal places. (If necessary, consult a list of formulas.) Lower limit: X 5 ? Upper limit
