Question 19

Test the claim that ui is less than u2. A random sample of size 24 yields = 17.98 and s = 1, while a
random sample of size 24 yields 2 = 18.6 and s = 1.6. Use a = 0.10.
1. The population distribution requirement for this test is:
O Need a normally distributed population since this is a T-test
O Need a normally distributed population since ni and n2 < 30
O None since this is a Z-test
O None since ni and n2 > 30
The hypotheses are:
O Ho:µ = µ2; Ha:µ # µ2
O Ho: µ1 < µ2; Ha: µ1 > µ2
O Ho:µ > µ2; Ha: µ1 < µ2
O Ho:p1 < p2; Ha:p1 > p2
O Ho:p1 = p2; Ha:p1 p2
O Ho:p1 > P2; Ha:p1 < P2
2. This is a O twoO leftO right tailed test and the distribution used is
O Z since testing two proportions
OZ since both o values are known
OT since both o values are not known
The Degrees of Freedom (use the simple estimate discussed in the notes, not the messy formula) are
ON/A; this is a Z-test
O 23
O 24

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 Do not reject Ho since P > a
O Reject Ho since P > a
O Do not reject Ho since P < a
O Reject Ho since P < a
The conclusion is:
O There is sufficient evidence to conclude that µi is less than µ2
O There is insufficient evidence to conclude that µi is less than µ2
O There is sufficient evidence to conclude that ui is not less than u2
O There is insufficient evidence to conclude that u, is not less than u
