Clarinex-D is a medication used to reduce allergy symptoms. In clinical trials of Clarinex-D, it was found that 5% of patients taking it experienced insomnia as a side effect. Suppose a random sample of 240 patients taking Clarinex-D is selected. Let x represent the number, out of 240, who experience insomnia as a side effect. a. Compute the mean and standard deviation for X. Show the formulas used. Round to 1 decimal place. b. Verify that the distribution of X will be approximately normally distributed. Indicate what condition is required and show that the condition is met. c. Compute the lower and upper bounds of the range of usual values of X. (6 pts.) Show the formulas used and all work. d. Would it be unusual for 20 in the sample to experience insomnia as a side effect? Base your answer on the interval found in part (f). Clarinex-D is a medication used to reduce allergy symptoms.
