Question

Can someone please answer?

Research Scenario: "In 1960, the average age at which males first married was 23.3 years. It is widely assumed that people are waiting longer to get married nowadays. Test that hypothesis at the .05 level of significance given that a current-year sample of 43 men was collected in which the average age at which they were first married was 24.2 years with a standard deviation of 5.3 years."

Question: What is the correct null hypothesis?

Question 37 options:

	H0:μ=.05{"version":"1.1","math":"H_0 : \mu =.05"}
	H0:μ=5.3{"version":"1.1","math":"H_0 : \mu =5.3"}
	H0:μ=23.3{"version":"1.1","math":"H_0 : \mu = 23.3"}
	H0:μ=24.2

Question: The correct alternate hypothesis is that

H0:μ>24.2{"version":"1.1","math":"H_0 : \mu > 24.2"}

Question 38 options:

	True
	False

Answer 1

37). the correct null hypothesis :-

38).False.

[ the alternative hypothesis will be :

24.2 is the sample mean..not the population mean ]
