Question

A researcher investigated whether people are spending more time watching Netflix or attending Zoom meetings. A group of 45 people who watch Netflix were spending a mean of 11.3 hours per week with a standard deviation of 2.8 hours. A group of 50 people who are attending Zoom meetings were spending a mean of 13 hours per week with a standard deviation of 4.1 hours.

Construct a 95% confidence interval for the difference between the two groups’ means.

Based on the interval, is there a significant difference between the number of hours people are spending watching Netflix and attending Zoom meetings? If there is a significant difference, which group has the greater mean? Explain.
