Question 450464: A random sample contains 23 observations. Determine the p-VALUE for each of the calculated test statistics below and state your decision about the null hypothesis in each part by comparing the p-VALUE to α = 0.05
Hø: μ = 50
Ha: μ ≠ 50
a. t = 1.7171
b. t = 2.5083
c. t = 1.3212
d. t = 2.2911
e. t = 1.51915

You can put this solution on YOUR website! A random sample contains 23 observations. Determine the p-VALUE for each of the calculated test statistics below and state your decision about the null hypothesis in each part by comparing the p-VALUE to α = 0.05
Hø: μ = 50
Ha: μ ≠ 50
a. t = 1.7171
p-value = 2*P(t>1.7171 when df = 22)
= 2*tcdf(1.7171,100,22)
= 2*0.05
= 0.1

Conclusion: Since the p-value is greater than 5%, fail to reject Ho.
============================================================================
Comment: The same procedure is used on each of "b" thru "e".
