Question
![According to a Pew Research Center study, in May 2011, 33% of all American adults had a smartphone (one which the user can use to read email and surf the Internet). A communications professor at a university believes this percentage is lower among community college students. She selects 359 community college students at random and finds that 152 of them have a smartphone. In testing the hypotheses:
Ho: p = 0.33 versus
Ha: p < 0.33
Do the hypothesis test. Use a level of significance of α = 0.05;
Use the unrounded values in Excel to find the answers for #3 and #4.
1. This is an example of a [_____] hypothesis test.
2. Find the standard error. [_____]
3. Find the z value. [_____]
4. Find the p-value. [_____]
