Answer:
The correct option are option 2 and option 4
Step-by-step explanation:
From the question we are told that
The sample size is n = 12
The test statistics is ![t \approx 1.434](https://tex.z-dn.net/?f=t%20%5Capprox%201.434)
The level of significance is ![\alpha = 0.05](https://tex.z-dn.net/?f=%5Calpha%20%3D%200.05)
The rejection region is t>1.796
The null hypothesis ![H_o: \mu_d=0](https://tex.z-dn.net/?f=H_o%3A%20%5Cmu_d%3D0)
The alternative hypothesis is ![H_a : \mu_d >0](https://tex.z-dn.net/?f=H_a%20%3A%20%5Cmu_d%20%3E0)
From the given values we see that t < 1.796(i.e 1.434 < 1.796 ) which implies that t is not within the rejection region
Hence we fail to reject the null hypothesis
The conclusion is that there is insufficient evidence to suggest that that the husbands are significantly older than the wife.
Ummmmmmm yeah..what is this
