PLEASE HELP ILL GIVE BRINLIEST TO WHOEVER HELPS ME Some newer phones provide a screen time summary, which shows the amount of screen time for a user in a given week. A student would like to estimate the mean screen time for all phone users. She asks a random sample of 50 students at her school to share their screen time for the past 24 hours. The mean screen time for the chosen students is 2.73 hours. Which statement is an appropriate interpretation of the results?

All students probably have screen times close to 2.73 hours.

To obtain a better estimate of mean screen time, more students should be surveyed.

Because of undercoverage, 2.73 likely underestimates the mean screen time of all phone users.

2.73 hours is a suitable estimate for mean screen time of all phone users because a random sample was taken.
