3. The STS (round to 3 decimals) is:
The P-value (round to 4 decimals) is:
4. The decision at a = 0.05 is:
O Do not reject Ho since P < a
O Do not reject Ho since P> a
O Reject Ho since P < a

1. The population distribution requirement for this test is:
O Need a normally distributed population since this is a T-test
O None since this is a Z-test
O Need a normally distributed population sincen and n2 < 30
O None since nį and n2 > 30
The hypotheses are:
Ο Ho: μι μ Ha: μι< μ2
O Ho:µ1 = µ2; Ha: µ1 µ2
O Ho:p1 < p2; Ha:p1 > p2
O Ho:p1 = p2; Ha: p1 p2
O Ho:µi < p2; Ha:µ1 > 42
O Ho:p 2 P2; Ha:p1 < P2
2. This is a O rightO twoO left tailed test and the distribution used is
O Z since testing two proportions
