Answer:
Option B:


Classification:
The hypothesis test is Two-tailed.
Step-by-step explanation:
The mean length of imprisonment for motor-vehicle theft offenders in this country is 22.1 months.
This means that the null hypothesis is that the mean is of 22.1 months, that is:

A hypothesis test is to be performed to determine whether the mean length of imprisonment for motor-vehicle theft offenders in this city differs from the national mean of 22.1 months.
At the alternate hypothesis, we test if this mean is different of 22.1, that is:

Which means that the answer is given by option b).
Which of the following is the correct classification of the hypothesis test?
We test if the mean is different from a value, which means that the hypothesis test is Two-tailed.
15 minus 9 is equal to 6 <span />
The probability of a baby being a boy is 0.514.
Nine baby births are selected and we have to find the probability that at last one of them is a girl.
P(At least one out of 9 is baby girl) = 1 - P(No baby girl)
= 1 - P(All 9 are baby boy)
= 1 - (0.514)^9
= 1 - 0.0025
= 0.9975
The probability that at least one out of 9 selected births is baby girl is 0.9975
Answer:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year.
Putting time into years for simplicity,
6 months / 12 months/year = 0.5 years.
Solving our equation:
A = 200(1 + (0.055 × 0.5)) = 205.5
A = $205.50
