Samantha is interested to see if people spend more time driving to work than driving to school.

Her hypotheses are:

H0: μ1≤μ2

HA: μ1>μ2

μ1 is equivalent to the mean amount of time people spend driving to work each week, while μ2 pertains to the average amount of time people spend driving to school each week.

Work    School

Sample mean 3.219 2.575

Standard deviation 3.235 1.768

Sample Size    8    8

Solve this confidence interval or hypothesis test problem using significance level a=0.05

Make sure that you use appropriate terminology and specify whether you are using the classical method or the p-value method.

People gain weight when they take in more energy from food than they expend. Researchers wanted to investigate the link between obesity and energy spent on daily activity. Choose 20 healthy volunteers who don't exercise. Deliberately choose 10 who are lean and 10 who are mildly obese but still healthy. Attach sensors that monitor the subjects' every move for 10 days. The table below presents data on the time (in minutes per day) that the subjects spent standing or walking,...
