The National Health and Nutrition Examination Survey (NHANES) indicates that more U.S. adults are becoming either overweight or obese, which is defined as having a body mass index (BMI) of 25 or more. Data from the Centers for Disease Control and Prevention (CDC) indicate that for females aged 35 to $55,$ the mean BMI is 25.12 with a standard deviation of $5.3 .$ In a similar study that examined female cardiovascular technologists who were registered in the United States and who were within the same age range, the following BMI scores resulted: Test the claim that the cardiovascular technologists have a lower average BMI than the general population. Use $\alpha=0.05$ a. Describe the parameter of interest. b. State the null and alternative hypotheses. c. Calculate the value for $z \star$ and find the $p$ -value. d. State your decision and conclusion using $\alpha=0.05$
