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