Kevin, a Human Resources professional, would like to make the claim that the average hourly wage for administrative workers at his company is less than $9.69. Kevin samples 15 workers and obtains a sample mean of $8.80 per hour. At the 1% significance level, should Kevin reject or fail to reject the null hypothesis given the sample data below?

The ___________ is a value used in making a decision about the null hypothesis and is found by converting the sample statistic to a score with the assumption that the null hypothesis is true.
If a p-value for your hypothesis testing about the population mean is 0.073 , and the level of significance used was 5%, then the conclusion would be to: Select one: a.

In a certain city, the population mean commute time to work was reported as 30 minutes. The director of human resources for a certain company in the city claimed the mean commute time for the company’s employees was greater than 30 minutes. The director surveyed 35 randomly selected employees and found that their mean commute time was 31.4 minutes. With all conditions for inference met, a hypothesis test conducted at the significance level α=0.05α=0.05 resulted in a pp-value of 0.381. Which of the following is an appropriate conclusion? The director has convincing statistical evidence to conclude that the population mean commute time is greater than 30 minutes. A The director has convincing statistical evidence to conclude that the population mean commute time is less than 30 minutes. B The director has convincing statistical evidence to conclude that the population mean commute time is 31.4 minutes. C The director does not have convincing…
