Ans:

Score
1 1112
2 1168
3 1210
4 1300
5 919
6 825
7 1210
8 917
Total= 8661
Average= 1082.625

Average=8661/8=1082.625

There were two students,who recevied same score i.e. 1210

Maximum score=1300

Minimum score=825

Range=Maximum-minimum=1300-825=475

Deviation from average score:

Score 1082.625-score
1 1112 -29.375
2 1168 -85.375
3 1210 -127.375
4 1300 -217.375
5 919 163.625
6 825 257.625
7 1210 -127.375
8 917 165.625

A researcher wants to determine whether high school students who attend an SAT preparation course score significantly different on the SAT than students who do not attend the preparation course. For those who do not attend the course, the population mean is 1050 (? = 1050). The 16 students who attend the preparation course average 1150 on the SAT, with a sample standard deviation of 300. On the basis of these data, can the researcher conclude that the preparation course...
