Suppose your marketing department feels like 36% of customers prefer a certain feature for a product. But you suspect that it is much less than this. To test your hypothesis you send surveys to a group of customers. You get 360 responses and of those only 30% say they prefer the feature. Suppose you want to test your hypothesis with a level of significance of .01 (1%). What is your conclusion? a) What is the null hypothesis? b) What is the alternative hypothesis? c) What is the claimed population proportion? d) What is the sample proportion (called the test statistic) e) What is the std deviation f) What is the z-value of the test statistic? g) What is the p-value h) compare your p-value to the level of significance i) What is the conclusion in words
