Prof Rea’s Exam Question 4. Show as much work as possible and clearly show all four steps of a hypothesis test to earn credit: Last year, researchers determined that the average cost for health insurance for an individual in the US was $605 per month. You wonder if the average monthly cost for health insurance has decreased since last year. You randomly survey 125 adults in the US and find that they spend an average of $585 per month on health insurance. You compute the sample standard deviation to be $82. Test your claim using a 5% level of significance. Round all calculated values to three decimal places.

Exаm Questiоn 3 The systоlic blоod pressure (given in mm Hg) of mаles hаs an approximately normal distribution with mean µ = 125 and standard deviation σ = 13. Label the tick marks on the horizontal axis using what you know about the normal distribution and noting that the distance between each tick mark is 1 standard deviation. Adam says that . Describe three mistakes that Adam made. Then explain to him how to fix them. Identify the systolic BPs that encompass approximately 95% of all systolic BP’s of males. Explain why.
