Answer:
See attached pictures.
Step-by-step explanation:
See attached pictures.
Since we are not given any information about the proportion, we will assume the sample proportion to be 0.50
so,
p = 0.50
The Error is 10% percentage point. This means that on either side of the population proportion the error is 5% so E = 0.05
z = 1.645 (Z value for 90% confidence interval)
The margin of error for population proportion is calculated as:
This means 271 students should be included in the sample
10 5/6 = 65/6
2 1/4 = 9/4
2 (9/4) = 9/2
So the length left is
65/6 - 9/2 =
65/6 - 27/6 =
38 / 6 =
19 / 3 =
6 1/3 in
