The t statistic for a test of
H0:=45
HA:<45
 based on n = 10 observations has the value t = -1.93.
(a) What are the degrees of freedom for this statistic?
(b) Using the appropriate table in your formula packet, bound the p-value as closely as possible:
 < p-value <
Solution
a) df = 10-1 = 9
b) t value = -1.93
p value for one tailed = .042836.
 
 0< p < .05.
