Question
Preliminary data analysis indicate that it is reasonable to use a -test to
carry out the specified hypothesis test. Perform the -test using the
critical-value approach.
a = 0.05 to test the claim that µ+35.8. The sample
Use a significance level of
data consists of 10 scores for which x=44.2 and s=7.3.
Ho : µ±44.2
Η : μ 44.2
Test statistic: t= 3.64. Critical values: t=±2.262. Reject Ho : u=44.2.
There is sufficient evidence to support the claim that the mean is different from 44.2.
HO : μ-35.8
H : u#35.8
Test statistic: t=3.64. Critical values: t=±2.262. Reject Ho : u= 35.8.
There is sufficient evidence to support the claim that the mean is different from 35.8.
Ho : µ+35.8
Η : μ-35.8
Test statistic: t= 3.64. Critical values: t=±2.262. Reject H, : µ= 35.8.
There is sufficient evidence to support the claim that the mean is different from 35.8.
H0: μ=44.2
H, : µ+44.2
Test statistic: t= 3.64. Critical values: t=±2.262. Reject H : u=
1=44.2.
There is sufficient evidence to support the claim that the mean is different from 44.2.
