The manager of a fast food chain performs a hypothesis test at the significance level of0.10to determine if the proportion,p, of the orders that are taken at the fast food window is less than33%. These are the null hypothesish and the alternative hypothesish for the test. ho:p=0.33 h₁:p<0.33 (to) The result of the manager's hypothesis test will be to reject or not reject the null hypothesis,ho.Yeahh is in fact true or false, fill in the following table to indicate whether the test result is correct, a type I error, or a type Il error. Declineh 0 do not rejectho h it's true (Choose an option) ▼ Error type I Error type II Correct Tehouse and option h it's false (Choose an option) ▼ (Choose an option) (b) The manager takes a random sample and determines that it is appropriate to use a Z test. The value of the test statistic isz=-1,654 (rounded to three decimal places). Draw the appropriate figure for the test.
