(1 point) In 2002 the Supreme Court ruled that schools could require random drug tests of students participating in competitive after-school activities such as athletics. Does drug testing reduce use of illegal drugs? A study compared two similar high schools in Oregon. Wahtonka High School tested athletes at random and Warrenton High School did not. In a confidential survey, 8 of 110 athletes at Wahtonka and 29 of 102 athletes at Warrenton said they were using drugs. Regard these athletes...

Hypothesis testing and confidence intervals are the most common inferential tools used in statistics. Imagine that you have been tasked with designing an experiment to determine reliably if a patient should be diagnosed with diabetes based on their blood test results. Create a short outline of your experiment, including all of the following: a) A detailed discussion of your experimental design. b) How is randomization used in your sampling or assignment strategy? c) The type of inferential test utilized in...

Q3. Hypothesis Testing with a Z Test (12 points) According to the CDC report, the mean life expectancy in the US population is currently (µ) 78.6 years with a standard deviation (σ) of 12. A researcher examined the age of death of 400 people recently recorded in several Arizona hospitals and calculated the mean to be 79.5 years old. He runs a two-tailed Z test with α = .05 to see if Arizona has a significantly different life expectancy compared...
