An ad for a new weight-loss program claims that participants lose an average of 12 pounds during their first month in the program. A skeptical medical professional believes that figure is too high, and wishes to conduct a hypothesis test at the=0.01

level of significance to determine if they are right. Suppose it is known that the population standard deviation for weight loss is 1.9 pounds.(Round your results to four decimal places)

Name the correct hypotheses for this test

A random sample of 37 participants lost an average of 9.8 pounds. Find the test statistic:

Give the P-value:

Which is the correct result:

• Reject the Null Hypothesis
• Do not Reject the Null Hypothesis

Give the conclusion

• There is not significant evidence to suggest that the actual mean weight loss for participants is less than 12
• There is significant evidence to suggest that the actual mean weight loss for participants is less than 12
