A researcher wants to test to see if husbands are significantly older than their wives. To do this, he collects the ages of husb

OLga [1]

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.

-2 3/4 ÷ -1/7= <br>help

Hitman42 [59]

The answer is 19 $\frac{1}{4}$

First you must set up the equation

$-2\frac{3}{4}$ ÷ $-\frac{1}{7}$

First, you must make the mixed number a improper fraction

$-\frac{11}{4}$ ÷ $-\frac{1}{7}$

Then you must divide

$\frac{77}{4}$

Finally, simplify

19 $\frac{1}{4}$
