A health researcher read the claim that  a 200-pound male can burn more than an average of 524 calories per hour playing tennis with a standard deviation of 45.9 calories. 37 males were randomly selected and the mean number of calories burnt per hour was 534.8. Test at 5% of level of significance whether the claim is correct? (Hint:  Right Tailed Test)

  1. State Null and Alternate Hypotheses.
  2. Apply test.
  3. Write your conclusion using critical value approach and p value approach.
  4. Construct a 95% confidence interval to estimate the population mean.  Write and justify your conclusion.

Solutions

Expert Solution

As confidence interval contains the population mean value it is conclude that the we fail to reject H0 and claim is false that the mean is greater than 524.
