PLEASE HELP! The mean life expectancy of a mosquito is 14 days. We believe the true mean is less than 14 days and plan a hypothesis test at the 5% significance level on a random sample of 60 of these mosquitoes. If the alternative hypothesis is correct, for which of the following values of mu is the power of the test greatest?

mu = 9
mu = 7
mu = 10
mu = 14
mu = 18

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04

step-by-step explanation:

the answer is d

hope this
