A schооl аdministrаtоr wonders if students whose first lаnguage is not English score higher on the math portion of the SAT exam than students whose first language is English. The mean SAT math score of students whose first language is English is 522, on the basis of data obtained from the College Board. A simple random sample of 20 students whose first language is not English results in a sample mean SAT math score of 516. SAT math scores are normally distributed, with a population standard deviation of 114. Determine the appropriate null and alternative hypotheses to assess whether students whose first language is not English score higher on the math portion of the SAT exam.
