PrOblem #13: Suppose that for people over 80 years of age there is a 20% chance that a Covid19 case requires [2 marks] hospitalization. In a random sample of 14 people over 80 years of age that have contracted Covid-19, let X be the number who require hospitalization. The below table is a probability distribution for X. @- IE E- @- Suppose that a group of 14 people over 80 years of age who have contracted Covid-19 are randomly selected, and 5 of them required hospitalization. Is this a signicantly high number that would suggest that the given percentage requiring hospitalization (i .e., 20%) is not correct? (A) Yes, because 5 is a lot more than expected. (B) Yes, because 0.086 is greater than .05. (C) No, because 0.0322 is less than .05. (D) No, because 0.086 is greater than .05. (E) No, because 0.1297 is greater than .05. (F) Yes, because 0.0322 is less than .05. (G) No, because 5 is not a lot more than expected. (H) Yes, because 0.1297 is greater than .05
