Step 1
From the given sample data : n=14 , , ƩX= 239
Now , the sample mean is ,
Also given that σ=3.7 , μ0=18 , α=0.01
Since , the population standard deviation (σ) is known.
Therefore , use normal-distribution.
Our aim is to test the claim that the average P\E rate of all large U.S. bank stocks is less than 18.
Here , we use the one sample mean Z-test.
