Complete Question

The complete is shown on the first uploaded image

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

    The level of significance is  \alpha = 0.05

    The  rejection region is    t>1.796

   The null hypothesis H_o: \mu_d=0

    The alternative hypothesis is  H_a : \mu_d >0

 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.
