Question
Assuming that you have a sample of n1 = 8, with the sample mean X1-42, and a sample standard deviation S1-4, and you have an independent sample of n2-15 from another population with a sample mean of X2-34 and a sample standard deviation S2-5 a. b. C. What is the value of the pooled-variance tSTAT test statistic for testing Ho:1 = 2? In finding the critical value, how many degrees of freedom are there? Using the level of significance = 0.01, what is the critical value for a one-tail test of hypothesis Ho: 1 What is your statistical decision? H2 against the alternative, 14: .> 2? d.Explanation / Answer
Assuming that you have a sample of , with the sample mean , and a sample standard deviation , and you have an independent sample of from another population with a sample mean of and a sample standard deviation =5,
What is the value of the pooled-variance test statistic for testing ?
pooled variance will be 5
In finding the critical value, how many degrees of freedom are there?
df = sample size - 1
creitical value for alpha = 0.05 is 1.64
Using the level of significance , what is the critical value for a one-tail test of hypothesis against the alternative,
What is your statistical decision?
since t value is greater than critical value we reject Ho
