The following data is the math test scores of students graduating from a particular high school . The government uses these scores to determine if there will be accreditation awarded. In order for this to occur the mean score must be above 780. A sample of students scores is drawn at random and they take the test. The scores are in the following table and the population is considered a normal distribution.   Test at the .01 level.

980

764

798

760

Five years ago, the average math SAT score for students at one school was 475. A teacher wants to perform a hypothesis test to determine whether the mean math SAT score of students at the school has improved. The mean math SAT score for a random sample of 40 students from this school is 469 with a standard deviation of 73. Do the data provide sufficient evidence to conclude that the mean math SAT score for students at the school...

A principal claims the students in his school have above-average test scores for a particular standardized test. A sample of 50 students from his school were found to have an average test score of 77.2. The population mean for test scores for this particular test is 75, with a standard deviation of 9 (so we can assume that the population test score is normally distributed). Set up a hypothesis test to determine whether this principal’s claim is correct (use alpha...
