Suppose it was found that in a random sample of 200 individuals who were underweight (defined as having a BMI of under 18.5), 8 of them were hospitalized with COVID-19. Of a corresponding group of 400 individuals who were classified as severely obese (defined as having a BMI of at least 45.0), 32 were hospitalized with COVID-19. (a) What are the two sample proportions (to 4 decimal places)? (b) What is the difference between the two sample proportions (to 4 decimal places)? (c) If you were testing whether the probability of being hospitalized with COVID-19 differed between the population of underweight individuals and the population of severely obese individuals, what would be your null hypothesis, either in words or in mathematical terms?
