Question

According to a study, 75% of adults ages 18-29 years had broadband Internet access at home in 2011. A researcher wanted to estimate the proportion of undergraduate college students (18-23 years) with access, so she randomly sampled 183 undergraduates and found that 160 had access. Estimate the true proportion with 99% confidence. Use a graphing calculator and round the answers to at least three decimal places.

          According to a study, 75% of adults
ages 18-29 years had broadband Internet access at home
in 2011. A researcher wanted to estimate the proportion of
undergraduate college students (18-23 years) with
access, so she randomly sampled 183 undergraduates and
found that 160 had access. Estimate the true proportion
with 99% confidence. Use a graphing calculator and round

Step 1

The sample proportion is calculated by dividing the number of successes (students with broadband access) by the total number of students sampled. \[ \hat{p} = \frac{160}{183} \] Show more…
