19. The Provo School District Superintendent would like to know parents thoughts on the transition to online instruction was during the pandemic in spring 2020. The superintendent sends out a survey to 500 randomly selected parents. Of the 500 surveys, 120 are returned, and of these 108 show that the parent was very dissatisfied with the transition to online instruction last spring. a. What is the rate of nonresponse for this survey? (1.5 pts) b. Suppose the rate of dissatisfaction among parents is estimated as 108 out of 120 or 90%. What is the likely direction of the bias if it exists? (1.5 pts) i. This is not a biased estimate of the rate of dissatisfaction among parents because it was based on a random sample. ii. This is not a biased estimate because the nonresponse rate can be accounted for with a margin of error. 111. The direction of the bias is likely to underestimate the rate of dissatisfaction among parents because parents without strong opinions are more likely to respond. iv. The direction of the bias is likely to overestimate the rate of dissatisfaction among parents because parents who are very angry are more likely to respond
