The average teaching salary in Georgia is $48,553 per year. The school districts in the metro Atlanta area boast that they pay more. A company that is running a career fair decides to take a random sample of 228 teachers from the metro Atlanta area and record their salaries. The sample mean is $49,021, with a standard deviation of $3,127. Do the data provide statistically significant evidence at the α = 0.05 level that the average teaching salary in the metro Atlanta area is greater than the state average? The P-value of this test is 0.0124. What is the correct interpretation of the P-value? There is a 1.24% chance that

Question
The average teaching salary in Georgia is $48,553 per year. The school districts in the metro Atlanta area boast that they pay more. A company that is running a career fair decides to take a random sample of 228 teachers from the metro Atlanta area and record their salaries. The sample
- The P-value of this test is 0.0124.
What is the correct interpretation of the P-value?
There is a 1.24% chance that the mean teaching salary in metro Atlanta is greater than $48,553.
Assuming that the mean teaching salary is $48,553, there is a 1.24% chance that the null hypothesis is true.
Assuming that the mean teaching salary is greater than $48,553, there is a 1.24% probability of getting a sample mean salary of $49,021 or more by chance alone.
Assuming that the mean teaching salary is $48,553, there is a 1.24% probability of getting a sample mean salary of $49,021 or more by chance alone.
