You have two options for question 1 below. Only do one of these options not both!!!

Q1 - Option A An aneroid sphygmomanometer is a mechanical device used to measure blood pressure. A random sample of these devices is tested for accuracy and the errors (measured in mm Hg) are listed below (based on data from ow Accurate Are Sphygmomanometers?y Mion and Pierin, Journal of Human Hypertension, Vol. 12, No. 4). A researcher believes that the true population standard deviation of sphygmomanometer errors is greater than 6 mm Hg. The researcher asks you to help conduct the appropriate test and report your results back to him.

acc=c(-4, -11, 5, 5, 8, 14, -16, -12, 4, 6, -6)

Q1 - Option B Sample times (hours) of sleep for randomly selected adult subjects included in the National Health and Nutrition Examination Study, are listed below. A common recommendation is that adults should sleep between 7 hours and 9 hours each night. The researchers claim that people are now sleeping less than 7 hours on average. The researchers want you to test to see if their claim is true?

ST=c(8.6, 7.3, 7.3, 6.8, 5.6, 6.5, 7.7, 6.2, 8.2, 6.1, 5.8, 5.2, 6.3, 7.2, 6.0, 6.2, 7.1, 6.8, 8.1, 6.6)
