Question

H0: = 5 and Ha: > 5

What does it mean if the p-value is 0.026. Interpret the p-value.

If the true population mean is 5, the probability of randomly selecting another sample of 400 patients whose sample mean is 5.2 or more is 0.026.

If the true population mean is 5, the probability of randomly selecting another sample of 400 patients whose sample mean is 5.2 is 0.026.   

If the true population mean is more than 5, the probability of randomly selecting another sample of 400 patients whose sample mean is 5.2 or more is 0.026.

If the true population mean is more than 5, the probability of randomly selecting another sample of 400 patients whose sample mean is 5.2 is 0.026.

None of the above

Explanation / Answer

InterpInterpre of p-value is.

If significance level is =alpha=0.05

So if p-value <0.05 then we reject Ho

If p-value >0.05 then we accept Ho

Here p-value =0.026<0.05

Surely here reject H0

If the true population mean is 5, the probability of randomly selecting another sample of 400 patients whose sample mean is 5.2 or more is 0.026.
