A professor records the difference between the marks scored by the students in the class test last week and those scored in the
dezoksy [38]

Answer: (10.82\ , 13.18)

Step-by-step explanation:

The confidence interval for population mean is given by :-

\mu\pm\ z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

Given : Sample size : n= 35  , large sample (n>30)

Mean difference : \overline{x}=12

Standard deviation : \sigma=3

Significance level : \alpha=- 1-0.999=0.001

Critical value : z_{\alpha/2}=z_{0.0005}=3.4807567

Now, the 99.9% confidence interval for the mean difference between the marks scored last week and marks scored this week by all the students will be :-

12\pm\ (3.4807567)\dfrac{2}{\sqrt{35}}\\\\=12\pm1.18\\\\=(10.82\ , 13.18)

Hence, the  99.9% confidence interval for the mean difference between the marks scored last week and marks scored this week by all the students = (10.82\ , 13.18)
