Try the following questions then match the answers below. Suppose in a sample of 100 customers that order a PS4 there are 52 that are male and you want to test the claim the proportion that are male is more than 50%. (a) What is the sample proportion of males? (b) What is the standard error of the sample proportion Note that in the final exam you will do the extra steps (c) what is the test stat (d) What is the p-value (e) What is the null and alternative hypothesis () What is the suitable conclusion Answers (c) test stat is 0.4 (d) p-value = Probability Z-0.450.3446 (In the exams students have to estimate this using a graph or look it up on a t-table) (e) Ho p=0.5 Hz p0.5 (1) The p-value is not less than the default significance level = 0.05 so do not reject Ho because there is not strong evidence the proportion is above 5076
(e) What is the null and alternative hypothesis ( What is the suitable conclusion Answers (c) test stat is 0.4 (d) p-value = Probability Z>0.4=0.3446 (In the exams students have to estimate this using a graph or look it up on a t-table) (e) Ho :p=0.5 H.:p> 0.5 (1) The p-value is not less than the default significance level a=0.05 so do not reject Ho because there is not strong evidence the proportion is above 50% What is the sample proportion Choose... - What is the standard error of the sample proportion Choose... - Next page
