Question

Find the p-value for the following hypothesis test. H 0 : μ = 20 , H 1 : μ < 20 , n = 64 , x ¯ = 18.75 , σ = 6.4.

Answer #1

this is a *left tailed
test.*

as the population sd is known we will do 1 sample z test for mean.

test statistic be:-

**p value
be:-**

Question 1
The p-value of a test H0: μ= 20 against the
alternative Ha: μ >20, using a sample of
size 25 is found to be 0.3215.
What conclusion can be made about the test at 5% level of
significance?
Group of answer choices
Accept the null hypothesis and the test is insignificant.
Reject the null hypothesis and the test is insignificant.
Reject the null hypothesis and the test is significant
