- Never Married People The percentage of males 18 years and older who have never married is 30.4 . For females the percentage is 23.6 . Looking at the records in a particular populous county, a random sample of 250 men showed that 73 had never married and 50 of 200 women had never married. At the 0.05 level of significance, is the proportion of men greater than the proportion of women? Use the P -value method and let p1 be the proportion of men.p3 answer only pls 21. what is the statistical decision 22. what is the conclusionA survey conducted on a group of 250 people randomly recruited from among the retirees revealed that 115 people were willing to find a new job. It is known that the rate of those who previously wanted to work among retired people is 67%. Can it be claimed that the ratio of these two tendencies is different from each other for the 2% significance level? Test it, interpret the decision you made as a result of the test. While testing the hypothesis test, apply the 4 stages and show them separately.
