Please explain throughly I'd like to understand! Thanks!

Netflix reports that the average user watches an average of 3.2 hours of content per day through their service. They suspect that the average is even higher for people who do not pay for their own account (and instead use an account of a friend or family member). Suppose a random sample of 20 such people is selected, yielding a mean of 3.5 hours watched and a standard deviation of 1.6 hours. Is there enough evidence to support the claim that people who do not pay for their own Netflix account average more than 3.2 hours of content per day? Use 0.05 as your significance level. You may assume the population is normally distributed. Be sure to report the p-value and write an interpretation in terms of the claim that we have been told to test
