The mean serum cholesterol concentration for a population is known to be 4.65 mmol/L. A random sample of smokers from this population is used to test the hypothesis that this group represents a different population with a different mean serum cholesterol. Identify the type I error that could occur in this scenario. a. Conducting a one-tailed test instead of a two-tailed test. b. Failing to reject the null hypothesis that u = 4.65 mmol/L for the smokers, when in reality y $ 4.65 mmol/L c. Rejecting y = 4.65 mmoV/L for the smokers, when in reality u = 4.65 mmol/L is true d. Using the wrong critical value
