The mean SAT math score of students whose first language is english is 516 on the basis of data obtained from the college board. A simple random sample of 20 students whose first language is not English result in a sample mean SAT math score of 522. SAT math score are normally distributed with a population standard deviation of 114. Why is it necessary for SAT math scores to be normally distributed to test the hypothesis?
- 2. What are the steps espoused by Applied Statistics in Business and Economics for formal hypothesis testing? Why is the sequence important?
