school students spend browsing their social media accounts. What might be the implication of
the results to the acadenmic performance of the senior high school students?
In item 1, suppose that the computed sample mean and sample standard deviation were based
on a sample of size n
length of time a senior high school student spends in a week browsing his or her social media
account(s). Compare the confidence intervals in items (1) and (2).
2.
100. Construct a 99% confidence interval for µ, the population average
3. Consider your answers in items 1 and 2. For a fixed confidence coefficient, how does the width
of the confidence interval relate to the sample size?

1. It has been observed that social media has been very attràctive to millennials and has been used
as a major platform where they can share their experiences, emotions, and others. A group of
senior high school students is interested to know the length of time a senior high school student
spends in a week browsing his or her social media account(s). The data gathered by the group
is recorded in the table below.
