In: Statistics and Probability
A one sample t test is conducted, with alternative hypothesis Ha: μ ≠ 36. There are 20 subjects from the sample and the test statistic calculated to be t = - 2.12. What is the p-value of the t test?
Group of answer choices
0.02 < p < 0.025
0.01 < p < 0.02
0.04 < p < 0.05
p > 0.5
We have here,
Sample size =n=20
Degree of freedom =n-1= 20-1=19
t=-2.12
|t| = 2.12
P value =0.0474...................by using Excel =TDIST(2.12,19,2)
0.04 < p < 0.05
