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

Solutions

Expert Solution

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
