2. Perform the following activity. Consider the whole grade 11 students as the population of interest. a. Record the length of time in a week which each student spends with his or her parents (or guardians) and siblings for the so-called bonding moments. b. Compute the population mean and population standard deviation of the length of time the students spend for bonding moments with their parents (or guardians) and siblings. c. Choose a random sample of 35. d. Compute the sample mean. e. Construct a 90% and a 95% confidence interval for the population mean. f. Do the 90% and 95% confidence intervals contain the average length of time in a week which the class spends with parents (or guardians) and siblings for bonding moments? 3. Based on your answers for the confidence intervals for 90% and 95% coefficients, how does the width of the interval relate to the confidence coefficients
