Answer:
a) Option A)
b) Point estimate of difference = -78
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $1,503
Sample mean, 
= $1,425
Sample size, n = 25
Sample standard deviation, s = $160
We have to carry a hypothesis test that the mean annual premium in Pennsylvania is lower than the national mean annual premium.
a) First, we design the null and the alternate hypothesis
b) Point estimate of the difference between the mean annual premium in Pennsylvania and the national mean
Point estimate of difference =
Mean annual premium in Pennsylvania - National mean
Thus,
Point estimate of difference = -78
Answer:
Step-by-step explanation:
two semicircles each of diameter 8 inches makes one circle with diameter=8 in.
radius r=8/2=4 in.
area of shaded region= πr^2=π×4²=16 π in²
≈16×3.14
≈50.24
≈50.2 in²
Answer:
4 girls have short red hair
Step-by-step explanation:
Total number of guests at the party is 32
1/2 of the guests are boys
The number of girls with long hair is
= 32×1/4
= 8 girls.
The number of girls with short blonde hair is:
= 16×1/4
= 4 girls
Therefore, we apply the formular below to calculate the maximum number of girls with short red hair.
Total number of girls- ( girls with long hair+ girls with short blonde hair)
= 16-(8+4)
=16-12
= 4
Thus, 4 girls have short red hair
