Question

Is it significant? The one–sample t statistic from a sample of n = 15 observations for the two-sided test of
H0: μ = 64

Ha: μ 64

has the value t = 2.12.
(a)

What are the degrees of freedom for t?
(b)

Locate the two critical values t* from Table C that bracket t. What are the two-sided P–values for these two entries?
(c)

Is the value t = 2.12 statistically significant at the 10% level? At the 5% level?
(d)

(Optional) If you have access to suitable technology, give the exact two-sided P–value for t = 2.12.

DOES ANYONE KNOW HOW FIND THE ANSWER FOR B?
