A large nationwide company with 1200 employees claims that the mean number of days missed by its employees due to illness is below the national average of 7. A random sample of 40 employees resulted in a mean of 6.6 days with a standard deviation of 1.8. The hypothesis test using α = 0.1 resulted in a p-value of 0.083. Which of the following statements is true? Group of answer choices There is a 8.3% chance that the mean number of days missed by employees at the company is below 7. If the mean number of days missed at the company is 7, the probability of obtaining a sample mean of 6.6 days or lower is 0.083. There is a 10% chance that the null hypothesis is true and a 8.3% chance that the alternative hypothesis is true. Since the probability that the mean number of days is below 7 is small, the null hypothesis is likely true.
