hold is 3.5 minutes. An employee of this company believes that customers
spend more than 3.5 minutes on hold. A random sample of n = 36 calls is
selected and the mean time the customers in this sample spent on hold was
5.15 minutes. All conditions for inference were met and the p-value for the
appropriate hypothesis test was 0.031. Which of the following statements is the
best interpretation of the p-value?

Respuesta :

Answer: If the null hypothesis is true, the probability of observing a sample mean of at least 5.15 minutes is .031

Step-by-step explanation:

MrRoyal

The interpretation of the p value is (e) the probability of observing a sample mean of at least 5.15 minutes is 0.031

The interpretation of the p-value

The p value is given as:

p = 0.031

Assume that the null hypothesis of the experiment is true (or accepted), then the interpretation of the p value is that the probability of observing a sample mean of at least 5.15 minutes is 0.031

Hence, the true statement is (e)
