The mean mathematics SAT score was 566 and the standard deviation was 126. A sample of 70 scores is chosen. Use table A.2.
Do you think it would be unusual for an individual to get a score greater than 567? Explain. Assume the variable is normally distributed.
Homework Answers
First find P(X>567)
= 
= P(Z>0.066)
USE Normal table, we get
= 0.435
It is not unusual because this Probability is greater than 0.05

Question 1 The average math SAT score is 511with a standard deviation of 119. A particular high school claims that its students have unusually high math SAT scores. A random sample of 50 students from this school was selected, and the mean math SAT score was 555. Is the high school justified in its claim?
