Click the icon to view the data table. ) What is the correlation coefficient over the whole week? The correlation coefficient isO Round to four decimal places as needed.) ) What is the correlation coefficient over the weekdays only? The correlation coefficient is Round to four decimal places as needed.) ) What is the correlation coefficient on the weekend? The correlation coefficient is Round to four decimal places as needed.) ) How realistic are the above correlation coefficients for analyzing whether the number of customers buying household items is related to the number taking breakfast? Make an assessment about the correlation in part (a). Choose the correct answer below. O A. The correlation in (a) is misleading since there is a single outlier in the data. O B. The correlation in (a) is statistically sound since both variables are quantitative and the relationship is linear. O C. The correlation in (a) is misleading since there are two clusters of data points instead of an overall trend.
