I'm stuck on how to solve this. I have included the data below. I thought for this answer I look at the Party Column for Independent answers. that column has only republican and democrat responses, no independent. I don't know how to solve this now. No other columns pertain to political preferences. Please help!
In 2014, Gallup conducted a poll where 42% of those surveyed said they were "Independents" (as opposed to Democrat or Republican). You take a random sample of 74 people at your campus. You believe that the percentage of Independents on your campus is lower than the 42% found in the Gallup poll. You want to test that claim. In your sample, 27 students said they were Independents.
Your Null Hypothesis is:Ho:p=0.42
Your Alternative Hypothesis is:Ha:p<0.42
Run a hypothesis test for proportions for this situation. Be sure that you carefully enter the value of 0.42 for both the null proportion value and for the alternative proportion value.
A) What is the sample proportion? Round four decimal places. B) What is the test statistic? This is labeled as Z-Stat. Round four decimal places.
C) What is the P-value for this test? Round to four decimal places.
