Miss Robrigado noted that the mean scores of a random sample of 15 Grade 8 students who had taken a special test were 80.5. If the standard deviation of the scores was 3.1 and the sample came from a population that is normally distributed with 95% confidence level, find the 1) point estimate, 2) margin of error and 3) interval estimate.

a.) What is the poient estimate of the population parameter?

b.) What is the value of the margin of error?

c.) What is the interval estimate population of the population parameter?

Thankyou!
