How would you solve the below?

Suppose a new standardized test is given to 97 randomly selected third-grade students in New Jersey. The sample average score on the test is 57 points, and the sample standard deviation, S_y , is 10 points. The authors plan to administer the test to all third-grade students in New Jersey.

The 95% confidence interval for the mean score of all New Jersey third graders is? (Rounded to two decimal points)

Suppose the same test is given to 194 randomly selected third graders from Iowa, producing a sample average of 61 points and sample standard deviation of 13 points

The 90% confidence interval for the difference in mean scores between Iowa and New Jersey is? (Rounded to two decimal points)

The p-value of the test of no difference in means versus some difference is? (Rounded to four decimal points)
