the top would be 6 x 4 = 24 and same for the bottom then I'll do the left amd right sides those are 20 and the front and back sides are 30 so I add all the sides so...

30 + 30 + 20 + 20 + 24 + 24 = 148

so 148 is our answer

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
