Select the correct choice below. O A. There is 90% confidence that the daily income for a weekday falls in the interval. O B. There is 90% confidence that the interval contains the mean income for each weekday. O C. There is 90% confidence that the mean income for each weekday will always fall in the interval. O D. There is 90% confidence that the daily income for all weekdays falls in the interval. d) Explain what "90% confidence" means in this context. Select the correct choice below. O A. 90% of all weekdays sampled have daily incomes that fall in the interval. O B. 90% of all samples of size 42 have a mean income for each weekday that is in the interval. O C. 90% of all weekdays have daily incomes that fall in the interval.
