- Please make sure the hypothesis is set up like this: Ho: Mew = value H1: mew < or > value for h1 I'm stuck on whether it is less than or greater than.solve for this with 6 step of hypothesis testingWhile her husband spent 2½ hours picking out new speakers, a statistician decided to determine whether the percent of men who enjoy shopping for electronic equipment is higher than the percent of women who enjoy shopping for electronic equipment. The population was Saturday afternoon shoppers. Out of 65 men, 21 said they enjoyed the activity. 5 of the 23 women surveyed claimed to enjoy the activity. Interpret the results of the survey. Conduct a hypothesis test at the 5% level. Let the subscript m = men and w = women.NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) State the distribution to use for the test. (Round your answer to four decimal places.)
