To investigate whether or not people tend to marry spouses of similar ages or whether husbands tend to be older than their wives
ira [324]

Answer:

See explanation below

Explanation:

1) Option C is correct.

The average difference in husband and wife marriage ages in Cumberland County; μd

2) Option D is correct.

Null: The average difference in marriage ages in Cumberland County is 0.

Alt: The average difference in marriage ages is greater than 0.

3) Option A is correct

Null: μd = 0

Alt: μd > 0

4) Given:

n = 24

d' = 1.875

Sd = 4.812

Find test statistic:

t = \frac{d'}{Sd/\sqrt{n}}

= \frac{1.875}{4.812/\sqrt{24}}

t = 1.909

Degree of freedom, df = n - 1 = 24 - 1 = 23

Pvalue = (t_2_3 > 1.909) = 0.0344

Pvalue = 0.0344

Significance level = 0.05

5) Since p value is less than significance level, reject null hypothesis H0

Hence, there is strong evidence that, on average, husbands are older than their wives in Cumberland County
