If, in a sample of n=20 selected from a normal
population, X bar=51 and S=12, what are the critical values of t if
the level of significance, α, is 0.10 the null hypothesis, H0,
is
μ=50, and the alternative hypothesis, H1, is μ not
equal to 50.
1. What are the critical values of t?
(round to four decimal places as needed(
Homework Answers
Given the sample size = 20. since the alternative hypothesis is two sided, therefore the critical value is find out with degree of freedom 19 and equal
,
