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

The height of the pyramid is equal to 1/2 of the length of a side on the base. Which formla represents the volume of the pyramid

Sav [38]

The volume of the pyramid is a third of the volume of the prism which has the same base area and height as the pyramid. That is,
V = b²h / 3
Substituting the variables given,
V = (s²)(0.5s) / 3
Simplifying,
V = s³/6
