Answer:
P-value = 0.019
Step-by-step explanation:
We are given ;
Null Hypothesis, : μ = 130
Alternate Hypothesis, : μ > 130
Also, the test statistics (t) is given to us as 2.33 and degree of freedom as 14.
P-value is given by = P( > 2.33) = 0.019 or 1.9% .
Therefore, the appropriate p-value is 0.019 .
Therefore it is inconsistent
The correct answer is D.
When finding the mean you find the average of the numbers. When these values are added together and then divided by he number of values, that is the end result.
12x=x+99
11x=99
x=9
therefor his age is 9
