Refer to Exercise 1. Another molecular biologist repeats the study with a different design. She makes up 12 DNA samples, and then chooses 6 at random to be treated with the enzyme and 6 to remain untreated. The results are as follows:
Enzyme present: 12 15 14 22 22 20
Enzyme absent: 23 39 37 18 26 24
Find a 95% confidence interval for the difference between the mean numbers of fragments.

ANSWER:Solution :
Step 1 of 1:
Given, a molecular biologist repeats the study with a different design.
Then a molecular biologist makes up 12 DNA samples and 6 treated with the enzyme.
We know that a molecular biologist divides 6 DNA sample into two parts.
First one is enzyme present and enzyme absent.
Then the data is given below.
