SAT scores are known to follow a normal distribution with a standard deviation of 100 points. Test the
claim that the population mean SAT score at ACME High School is more than at ACE High School. A random
sample of 34 ACME students yields 1 = 1063 and a random sample of 30 ACE yields 2 = 1010. Use a =
0.10, and let ACME be Population 1.
1. The sample size requirement for this test is:
ON/A since the populations are normally distributed
O Sample sizes must both be at least thirty since this is a Z-test
O Sample sizes must both be at least thirty since this is a T-test
ON/A since this is a Z-test
The hypotheses are:
O Ho:p1 < P2; Ha:p1 >
O Ho: µi < µ2; Ha:µ1 > µ2
O Ho:p1 > P2; Ha:p1 < p2
O Ho: µ1 = µ2; Ha:µ1 # µ2
O Ho:µ > µ2; Ha:µ1 < µz
O Ho:p1 = P2; Ha:P1 # P2
2. This is a O leftO twoO right tailed test and the distribution used is
OZ since testing two proportions
OT since both o values are not known
O z since both o values are known
The Degrees of Freedom are
O 29
O 34
ON/A; this is a Z-test

3. The STS (round to 3 decimals) is:
The P-value (round to 4 decimals) is:
4. The decision at a = 0.10 is:
O Reject Ho since P < a
O Reject Ho since P > a
O Do not reject Ho since P < a
O Do not reject Ho since P > a
The conclusion is:
O There is sufficient evidence to support the claim that the mean SAT score at ACME is more than at
ACE
O There is insufficient evidence to support the claim that the mean SAT score at ACME is more than at
ACE
O There is insufficient evidence to reject the claim that the mean salary at ACME is more than at ACE
O There is sufficient evidence to reject the claim that the mean SAT score at ACME is more than at ACE
