From the Behavioral Risk Factor Surveillance System in 2019, the prevalence of self-reported obesity among Michigan adult residents was 35.0%. Moreover, nationalreports from American Heart Association and Mayo Clinic state that people are moreinactive than they used to because of the COVID-19 preventive measures. With this,you are hypothesizing that this year, the proportion of people categorized as obese ishigher than before. To verify this, a random sample of 245 individuals were randomlyselected from the different counties. Out of the sample, 98 of them were classifiedas obese.
