1. Data was collected containing the weight of 40 individuals (20 women and 20 men). This sample was being used to test a new weight loss drug so researchers wanted to know before assigning participants to the drug/placebo, if females in the sample weighed less than males. ( = 0.05)
   • Complete test, check all conditions and assumptions, and write out the 6 steps
     • Include appropriate output
   • Would it be appropriate to estimate and interpret the effect size?
   • If appropriate, estimate and interpret the effect size.
2. Recovery A sample of 193 polish volunteers were studied to measure immune efficacy. The researchers wanted to know whether Phagocytic uptake of particles by immune cells differed for males vs females. Test that there is a difference in the phagocytic uptake between genders. Data is stored in the height_immunity data set. ( = 0.01)
   • Complete test, check all conditions and assumptions, and write out the 6 steps
     • Include appropriate output
   • Draw out the distribution
   • Would it be appropriate to estimate and interpret the effect size?
   • If appropriate, estimate and interpret the effect size.
