Question
The data shown represent the age (in weeks) at which babies first crawl, based on a survey of 12 mothers. Complete parts (a) and (b). (a) Draw a boxplot to check for outliers. Choose the correct answer below. OA. + 20 30 40 50 60 Q Q OB. 20 30 40 50 60 Q Q (b) Construct and interpret a 95% confidence interval for the mean age at which a baby first crawls. Does the boxplot suggest that it is reasonable to construct a confidence interval for the population mean? OA. Yes, because the distribution is roughly symmetric with no outliers. OB. No, because the distribution is symmetric with no outliers. OC. No, because the boxplot shows there are outliers. O D. Yes, because the distribution is highly skewed with outliers. O C.

Select the correct choice below and fill in the answer boxes to complete your choice. (Round to one decimal place as needed. Use ascending order.) OA. There is a 95% probability that the mean age at which a baby first crawls is between weeks and O B. We are 95% confident that the mean age at which a baby first crawls is between OC. The confidence interval should not be constructed. weeks weeks and weeks.
