The onesample t statistic for testing the hypotheses below f

The one-sample t statistic for testing the hypotheses below from a sample of n = 29 observations has the value t = 1.59.

H_o: ? = 0
H_a: ? > 0

(a) What are the degrees of freedom for this statistic?
df =  

(b) Give the two critical values t * from Table C that bracket t. (Use 3 decimal places.)
< t <  

What are the one-sided P-values for these two entries?
< P-value <  
(c) Is the value t = 1.59 significant at the 5% level?

Yes No    

Is it significant at the 1% level?

Yes No   

Solution

df = 28

Critical value t at 0.05 level = 1.7011 (for one tailed)

P values are 0

c) p value for t = 1.59

is 0.0615

As p value >0.05

accept null hypothesis.

At 0.01% level also p >0.01, hence not significant.
