A researcher is conducting a pilot study on physical activity in healthy older adults, and is measuring the number of minutes of elevated heart rate that the participants attain over the course of seven days. The researcher is particularly interested in the role that gender plays in exercise, and has sorted her data by gender.

Number of minutes for females: 98, 49, 55, 303, 60, 75, 59, 121, 95, 99, 27, 50, 62, 70, 86, 126, 138, 111, 86, 69

Number of minutes for males: 78, 98, 155, 51, 71, 129, 125, 20, 110, 98, 140, 131, 88, 90, 105, 110, 86, 90, 145, 155

Assume that the data in problem number 1 above were obtained using random sampling. Test the hypothesis (writing out the 5 steps) that males had more minutes of exercise than did females.

Physical activity of obese young adults. In a study on the physical activity of young adults, pediatric researchers measured overall physical activity as the total number of registered movements (counts) over a period of time and then computed the number of counts per minute (cpm) for each subject (International Journal of Obesity, Jan. 2007). The study revealed that the overall physical activity of obese young adults has a mean of μ = 320 cpm μ = 320   cpm and a...

In a study on the physical activity of people, researchers measured overall physical activity as the total number of registered movements (counts) over a period of time and then computed the number of counts per minute (cpm) for each subject. The study revealed that the overall physical activity of obese people has a mean of μ=322cpm and a standard deviation σ=92cpm. In a random sample of 100 obese people, consider x ̅, the sample mean counts per minute. Now suppose...
