Step 1

In this question, data about the two samples has been given, using that information we have to conduct a hypothesis test and find Confidence interval at 90% level of significance.

Given information is on whiteboard.

Step 2

In this part we have calculated the sample mean and sample standard deviation and then we have calculated the poooled sample standard devition.

Calculations shown on whiteboard.

Step 3

In this part we have calculated conducted hypothesis test.

- Since P Value is greater than level of significance 0.025.
- Which shows that we do not have enough evidence to reject the n...
