7/8 first week
3/2 second week = 12/8 total
12/8 - 7/8 = 5/8 second week
7/8 first, 5/8 second, therefor 3/8 for the third week.
3/2 + 3/8 = total in third week
12/8 + 3/8 = 15/8 = 1 7/8 total in third week
12 in front and 12 in back.
Answer: The point estimate of the population mean is <u>23</u>. The margin of error for the confidence interval is <u>2</u>.
Step-by-step explanation:
The confidence interval for the mean is of the form is given by :-

Given : Lower bound:
Upper bound :
Then ,the sum of lower and upper bound will be :-

Since

Hence, The point estimate of the population mean is <u>23</u>. The margin of error for the confidence interval is <u>2</u>.
