Q:
# A test of H0: μ = 20 versus Ha: μ > 20 will be based on a random sample of size n from a normal population distribution. What conclusion is appropriate in each of the following situations? (Round your P-values to three decimal places.) (a) z = 3.3, α = 0.05

Accepted Solution

A:

Answer:We will accept the null hypothesis Step-by-step explanation:Given :[tex]H_0: \mu= 20[/tex] [tex]H_a: \mu> 20[/tex]To Find : What conclusion is appropriate in each of the following situations? Solution :z = 3.3, α = 0.05So, first we will find the p value corresponding to z value in the z table So, p-value is 0.999Since p value is greater than Alpha0.999>0.05So, we will accept the null hypothesis So, the population mean is 20
