Statistics professor recently graded final exams for students in her introductory statistics course. in a review of her grading, she found the mean score out of 100 points was a x¯=77, with a margin of error of 10. construct a confidence interval for the mean score (out of 100 points) on the final exam.

(67,87)

Step-by-step explanation:

The confidence interval for population mean is given by :-

, where is the sample mean and E is the margin of error.

Given : Sample mean :

Margin of error : E=10

Then, the confidence interval for population mean will be :-

Hence, the confidence interval for population mean =(67,87)

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
