The onesample t statistic for a test of H015 Ha

The one-sample t statistic for a test of H0:=15 Ha:<15 based on n = 5 observations has the value t = -1.248. (a) What are the degrees of freedom for this statistic? (b) Between what two probabilities P from a t-table does the P-value of this statistic fall? (State the smaller probability in the left box.) to

Solution

a)

df = 5-1=4

b)

using tables we will find a value of p value between 0.25 and 0.10
