An article investigated the consumption of caffeine among women. A sample of 43 women were asked to monitor their caffeine intake over the course of one day. The mean amount of caffeine consumed in the sample of women was 233.235 mg with a standard deviation of 221 .728 mg. In the article, researchers would like to include a 95% confidence interval. 0 The values below are t critical point - corresponding to 90%, 95%, 98%, and 99% confidence. Which critical point corresponds to 95% condence? 2 02.698 02.018 02418 O 1.682 Q? ' With 95% confidence, we estimate the mean amount of caffeine consumed by women is between 222.829 3mg and 243.640 8mg. (Round the limits of your interval to 4 decimal places.) 0 If the level of confidence were changed to 90%, what effect would this have on the width of the calculated confidence interval? Othe interval would widen Othere would be no effect on the interval { Othe interval would narrow
