Question

5. (A) For each of the following situations, suppose Ho = 2 is being tested against HA : 1 > 2. Find the P-value. State whether or not there is a significant evidence for HA- (1) ts = 2.123 with 3 degrees of freedom, a = 0.05. (11) ts = 2.734 with 7 degrees of freedom, = 0.01. (B) For each of the following situations, suppose Ho : 1 = 2 is being tested against HA : 1 2-Find the P-value. State whether or not there is a significant evidence for HA. (1) t. = 2.834 with 5 degrees of freedom, = 0.05. (11) 1.-2.834 with 5 degrees of freedom, = 0.01.

Explanation / Answer

Q 5) A)

I) The P-Value is .061915

Since p value is greater than level of significance, we Reject H0, and we have significant evidence for HA

II) The P-Value is .014585

Since p value is greater than level of significance, we Reject H0, and we have significant evidence for HA

B)

I) The P-Value is .036503

Since p value is less than level of significance, we Fail to Reject H0, and we donot have significant evidence for HA

II) The P-Value is .036503

Since p value is greater than level of significance, we Reject H0, and we have significant evidence for HA
