If the sample mean and sample standard deviation are the same when doing a study with an unknown mean and standard deviation of the population. What effect does increasing the sample size have on The P value and the margin of error (assuming the same confidence level)? Also, what effect does increasing the sample size have on the width of the confidence interval (assuming the same confidence level)?

    Statistics Grades: The statistics grades in the fall semester had mean of 65. The SRS were taken from different statistics groups (A, B, C and D) considering that the total number of students that took part on the exam was 110. Assuming that the change in the grades has a normal distribution with standard deviation σ= 10, We computed a 90% confidence interval of the mean change in score μ in the population of all statistics students. A) Find a...
