**Waiting Time Analysis for Pharmacy Customers**A study involving a random sample of 16 pharmacy customers was conducted to observe their waiting times in minutes. The collected data is as follows:- Waiting Times (in minutes): 22, 18, 12, 16, 13, 15, 17, 25, 17, 15, 19, 12, 16, 17, 14, 21**Task:**Calculate a 90% confidence interval for the average waiting time (\( \mu \)), assuming that the sample is from a normal distribution. Your answer should be rounded to 3 decimal places for the confidence interval and 4 decimal places for the t-value.**Instructions:**- Click [here](#) to access the Excel Data File, which provides additional data for calculations.**Visual Explanation:**- The image contains a horizontal box labeled “The 90% confidence interval,” with space to input the calculated results. This suggests using statistical software or manual calculation methods to derive the confidence interval and enter the values in the provided space.By completing this task, you'll better understand how to estimate population parameters and apply statistical concepts using confidence intervals.

Heights for teenage boys and girls were calculated. The mean height for the sample of 51 boys was 183 cm and the variance was 66. For the sample of 71 girls, the mean was 173 cm and the variance was 61. There is no reason to assume the variances would be equal. Estimate how much taller teenage boys are using a 87% confidence level. Express this in the (point estimate) ± (margin of error) format. Round answers to 2 decimal places. H
