A random sample of 78 students were interviewed and 59 said they would vote for the in the 2021 election. Let p represent the proportion of all students at this college who will vote for this candidate.1. Find the point estimate for p (state symbol and value)2. What distribution will you use for this confidence interval? 3. Indicate the critical value for a 90% confidence interval for p4. Calculate the standard error for this sample.5. Calculate the Maximal Margin of Error for the confidence interval. 6. Using the above calculations find a 90% confidence interval for p. 7. The campaign that hired your firm wants a confidence interval with a Maximal Margin of Error (E) of 0.05. How many students need to be interviewed for the sample to have an E of 0.05?
