Ho: u= 16.2 Hai u< 16.2 Test the hypothesis on the following data: 12, 15, 16, 10, 21, 23. 9. Use a = 16.


Expert Answer

Step 1

Given data

The null hypothesis is:

Hµ = 16.2

The alternative hypothesis is:

H1 :  µ   <  16.2


12, 15 , 16 ,10 , 21 , 23

Sample mean = 16.167

Sample standard deviation

6 126.833 5.0365 S = 5 1 п — 1

Step 2

Sample size n < 30 and population standard deviation is unknown, we will use one sample t-test
