solve it correctly please. I ll rate accordingly.

Suppose that you are testing the hypotheses Ho: p =0.20 vs. HA: p #0.20. A sample of size 350 results in a sample proportion of 0.25. a) Construct a 90% confidence interval for p. b) Based on the confidence interval, can you reject Ho at a = 0.107 Explain. c) What is the difference between the standard error and standard deviation of the sample proportion? d) Which is used in computing the confidence interval? a) The 90% confidence interval for p is (.20 .20 ) (Round to three decimal places as needed.)
