6. Jennifer's manager Dr. Jonathan Steinberg wonders whether Healthy Life members needed more chiropractic help in 2020 than in 2019, on average. Jennifer selected a random sample of those who were treated by chiropractic doctors in both years. The data are provided in the data file. Please help Jennifer Nguyen to test whether number of visits increased, on average. Also test whether annual expenses increased, on average. For both hypothesis tests, use Data Analysis t-Test: Paired Two Sample for Means and 2% significance level. Jennifer Nguyen and her manager know that in both cases differences are normally distributed, so here again there is no need to build histograms.
