In a ready to serve dinner preparation study of 10 trials of a new meal, the sample mean time for preparation was 18.5 min. and a sample standard deviation of 5.9 min. Prep time can be assumed normally distributed. Test whether the new meal meets the standard for having a preparation time below the 20 min. standard. Use 1% significance level. | What is the CONCLUSION for the study if H0: mean=20 min.? 1) Reject H0 and conclude preparation time is below 20 min. 2) Fail to Reject H0 and conclude the preparation time is below 20 min. 3) Reject H0 and conclude the preparation time does not differ from 20 min. 4) Fail to Reject H0 and conclude the preparation time does not differ from 20 min. 5) Fail to Reject the alternative H1 and conclude H0 is true. 6) No answer is correct. ------------------------------------- Enter: Integer 1, 2, 3, 4, 5, 6 no decimal
