Answer:

To find the radius, just take half of the diameter. The answer is 2.

Step-by-step explanation:

Semicircle Area and Perimeter

Area (A)

6.2832in²

A = πr²/2 = 2 * π [in²] ≈ 6.2832 [in²]

Perimeter (L)

10.2832 in

L = πr + d = 2 * π + 4 [inch] ≈ 10.2832 [inch]

Null hypothesis:

H0: μ(new) - μ(regular) = 0

Alternate hypothesis:

H1: μ(new) - μ(regular) > 0

The consumer is testing to know if his new detergent is better off in cleaning than the regular. The question says that higher scores after cleaning is used to signify which is better based on sufficiently clean garment. Since he is interested in knowing the mean scores of the differences, he should use the hypothesis I stated above.
