Newborn babies: A study conducted by the Center for Population Economics at the University of Chicago studied the birth weights of 752 babies born in New York. The mean weight was 3176 grams with a standard deviation of 840 grams. Assume that birth weight data are approximately bell-shaped. Estimate the number of newborns who weighed between 1496 grams and 4856 grams. Round to the nearest whole number. The number of newborns who weighed between 1496 grams and 4856 grams is

Español The producer of a weight-loss pill advertises that people who use the pill lose, after one week, an average (mean) of 1.85 pounds with a standard deviation of 0.95 pounds. In a recent study, a group of 55 people who used this pill were interviewed. The study revealed that these people lost a mean of 1.9 pounds after one week. If the producer's claim is correct, what is the probability that the mean weight loss after one week on this pill for a random sample of 55 individuals will be 1.9 pounds or more?
