Before cell telephones became so common, the average telephone charge per registered group was at least $5.00. Laura suspects that the average has dropped. Test H0: m > 5 and Ha: m < 5 using a .05 level of significance. Use both the critical value and p-value approaches to hypothesis testing. 2. In the past, Laura has made some important managerial decisions based on the assumption that the average number of people in a registered group is 2.5. Now she wonders if the assumption is…

According to the Philippine Statistics Authority's 2017 National Demographic and Health Survey, one in every four Filipino women between the ages of 15 and 49 has been subjected to physical, emotional, or sexual assault by their husband or partner. The approximate number of complaints received per day by the Violence Against Women and Children (VAWC) Desk in Pangasinan during the first quarter of 2020 is shown below. Find the mean, variance, and standard deviation of the distribution.

“The US Centers for Disease Control and Prevention said about 72 million Americans—nearly one out of every four of the country’s 304 million residents—are considered obese. Millions more are designated as overweight.” The American trend toward obesity has prompted many physicians to offer weight-loss programs to their patients. [Source: Price, W. T. “Physicians Get into the Weight-Loss Business.” Florida Today, July 7, 2008.] A physician conducted an experimental study to compare the effectiveness of four different weight-loss programs. In the study, 64 obese adults were randomly assigned to the four programs so that each program had 16 adults. The programs lasted for six months. The weights of the subjects were measured before and after the programs, and each subject’s weight loss was computed in pounds. The following table summarizes the results of the study, giving the number of observations and the sample mean and variance of the subjects’ weight loss in each program.…
