the next 3 questions concern the results of a survey of 18,000 adults between 20 and 64 years of age. Respondents were asked to indicate whether they would endorse a public health initiative. After data were collected, the distribution of the probability of endorsing the initiative was assessed.The distribution was judged to be roughly positively skewed Four potential plots of these data are presented below (only one is correct):9. If the survey included all adults aged 18+, one more category would be inserted at the low end of the age range. What would it be? d. 18-20c. 18-19b. 15-20a. 15-19
