Step-by-step explanation:
let's assume one month is 30 days you would multiply 10 by 30.

which would be 300 hours in 1 month
now if one month is 31 days you would simply multiply 10 by 31.

which would be 310 hours
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
im not sure but its either A Or D
Step-by-step explanation:
because the points are on that point
36 I believe sorry if it’s wrong what I did was multiply 2x 18 have I nice day good luck!
