Question
The mean SAT score in mathematics, u, is 586. The standard deviation of these scores is 29. A special preparation course claims that its graduates will score
higher, on average, than the mean score 586. A random sample of 50 students completed the course, and their mean SAT score in mathematics was 588. At
the 0,1 level of significance, can we conclude that the preparation course does what it daims? Assume that the standard deviation of the scores of course
graduates is also 29.
Perform a one-tailed test. Then complete the parts below.
Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.)
(a) State the null hypothesis H, and the alterative hypothesis H.
H, :
H, :1
(b) Determine the type of test statistic to use.
(Choose one) ▼
D=0
OSO
(c) Find the value of the test statistic. (Round to three or more decimal places.)
(d) Find the p-value. (Round to three or more decimal places.)
(e) Can we support the preparation course's claim that its graduates score
higher in SAT?
