Answer:
h = 3
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by its reciprocal.
So h / (1/2) is the same as h * 2 or 2h
2h = 6
Divide both sides by 2 to isolate the variable h.
2h/2 = 6/2
h = 6/2
h = 3

Answer:
The 90% CI for p is (0.53, 0.83)
Step-by-step explanation:
We have to develop a 90% confidence interval for the proportion of all students at the college that have met with a counselor to develop an educational plan.
We have a sample of size 25, where the sample proportion is:

The critical value of z for a 90% CI is z=1.645.
The margin of error is then:

Then, the lower and upper bound of the confidence interval are:

The 90% CI for p is (0.53, 0.83)
