O A. No, because there are not enough values to make a determination. O B. No, because the plotted values are not linear. O C. Yes, because the plotted values are not linear. O D. Yes, because the plotted values are approximately linear. (b) Draw a boxplot to check for outliers. Choose the correct answer below. O A. O B. O C. O D. + + + +Does the boxplot suggest that there are outliers? O A. No, there are no points that are outside of the 1.5(IQR) boundary. O B. Yes, there is at least one point that is greater than the third quartile or less than the first quartile. O C. Yes, there is at least one point that is outside of the 1.5(IQR) boundary. O D. No, there are no points that are greater than the third quartile or less than the first quartile. (c) Construct and interpret a 95% confidence interval for the mean age at which a baby first crawls. Select the correct choice and fill in the answer boxes to complete your choice. (Round to one decimal place as needed.) O A. The lower bound is weeks and the upper bound is weeks. We are 95% confident that the mean age at which a baby first crawls is outside of the confidence interval. O B. The lower bound is weeks and the upper bound is weeks. We are 95% confident that the mean age at which a baby first crawls is within the confidence interval
