Question

Preliminary data analysis indicate that it is reasonable to use a 

t

-test to carry out the specified hypothesis test. Perform the 

t

-test using the critical-value approach.

Use a significance level of 

=α0.05

 to test the claim that 

≠μ30.5

. The sample data consists of 

10

 scores for which 

=x36.2

 and 

=s7.9

.

 
 
H0
 : 
=μ36.2

H1
 : 
≠μ36.2

Test statistic: 
=t2.28
. Critical values: 
=t±2.262
. Reject 
H0
 : 
=μ36.2
.
There is sufficient evidence to support the claim that the mean is different from 
36.2
.
 
 
H0
 : 
=μ30.5

H1
 : 
≠μ30.5

Test statistic: 
=t2.28
. Critical values: 
=t±2.262
. Reject 
H0
 : 
=μ30.5
.
There is sufficient evidence to support the claim that the mean is different from 
30.5
.
 
 
H0
 : 
≠μ36.2

. Reject 
H0
 : 
=μ36.2
.
There is sufficient evidence to support the claim that the mean is different from
