Assign 9. #9 PLEASE SHOW ALL WORK

From a one-sample t test for testing the hypotheses below, a sample of n = 11 observations has attest statistic = 1.75. H0: mu = 0 Ha: mu > 0 What are the degrees of freedom for this statistic? From the t table what values does the P-value fall between? Is the t test statistic = 1.75 significant at the 5% level? Is it significant at the 1% level?

Solution

a)

df = n - 1 = 11 - 1

df = 10 [answer]

***************

b) At df = 10, t = 1.75 has a P value of, using a table,

0.05 < P value < 0.10 [answer]

*********************

c)

No. [answer]

It is significant if it is P < 0.05, but it is not.

******************

d)

No. [answer]

It is significant if it is P < 0.01, but it is not.
