Answer:
The answer is "0.0023 and Choice a"
Step-by-step explanation:
In point a:
The central limit theorem:
In point b:
The chance is lower than 0.05. This means that it is very rare to see the average sample above 251.8 if the argument is valid, that is why the means of the sample is far away from the common claimed and casts doubt on the actual mean.
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 .
