Answer:
The reasonable range for the population mean is (61%, 75%).
Step-by-step explanation:
The interval estimate of a population parameter is an interval of values that consist of the values within which the true value of the parameter lies with a certain probability.
The mean of the sampling distribution of sample proportion is,
.
One of the best interval estimate of population proportion is the 95% confidence interval for proportion,

Given:
n = 150
= 0.68
The critical value of <em>z</em> for 95% confidence level is:

Compute the 95% confidence interval for proportion as follows:


Thus, the reasonable range for the population mean is (61%, 75%).
1 is A, 2 is B, 4 is C, 5 is B, 6 is C, cant answer 4 bc it’s cut off
The whole length of the poster is 4 feet. There are three people who will paint an equal length, so this means that we need to divide the 4 feet of the poster between 3 people.
4 ÷ 3 <span>≈ 1.3
Each student will paint 1.3 feet, or 1 foot and 4 inches of the poster.</span>
