Use the sample data shown above to decide whether 41 is less than 42 at a = 0.05.
Make sure you are looking at ALL the data.
1. The population distribution requirement for this test is:
O None since this is a Z-test
O Need a normally distributed population since this is a T-test
O Need a normally distributed population since n1 and n2 < 30
O None sincen and n2 > 30
The hypotheses are:
O Ho:p1 < p2; Ha:p1 > p2
or
O Ho:p = P2; Ha:pi + p2
Ο Ho: μι < μ2 Ha: μι > μ2
O Ho:p 2 12; Ha:pi < p2
O Ho:µ1 = p2; Ha:µ1 + 42
O Ho:p1 > P2; Ha:pi < p2
2. This is a O twoO rightO left tailed test and the distribution used is
OZ since both a values are known
OT since both a values are not known
OZ since testing two proportions
The Degrees of Freedom (use the simple estimate discussed in the notes, not the messy formula) are
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 = 0.05 is:
O Do not reject Ho since P < a
O Do not reject Ho since P> a
O Reject Ho since P< a
O Reject Ho since P > a
The conclusion is:
O There is sufficient evidence to conclude that u, is not less than u
O There is insufficient evidence to conclude that u is less than uz
O There is sufficient evidence to conclude that u, is less than 42
O There is insufficient evidence to conclude that u is not less than u2
