Question

*50 PTS, WILL MARK BRAINLIEST*
Wellness pharmaceutical company claims that their new children's vitamin reduces the number of days that a child is sick in a year. To test this claim, a consumer reporter, Elizabeth, decided to conduct an experiment. She randomly selected 500 children and administered the Wellness children's vitamin to 250 of the children. Elizabeth then administered a placebo to the remaining 250 children.

After observing the children for one year, Elizabeth reported that, on average, children who received the Wellness children's vitamin were sick three days more than the average number of days a child is sick in a year. Elizabeth also found that, on average, the children who received the placebo were sick one day less than the average number of days a child is sick in a year.

What can be concluded from Elizabeth's report?
A.
Wellness pharmaceutical company's claim is true; therefore, it can be concluded that the Wellness children's vitamin reduces the number of days a child is sick in a year.

B.
Wellness pharmaceutical company's claim is false; therefore, it can be concluded that the Wellness children's vitamin reduces the number of days a child is sick in a year.

C.
Wellness pharmaceutical company's claim is true; therefore, it can be concluded that the Wellness children's vitamin does not reduce the number of days a child is sick in a year.

D.
Wellness pharmaceutical company's claim is false; therefore, it can be concluded that the Wellness children's vitamin does not reduce the number of days a child is sick in a year.

Answer 1

The answer is D, the vitamins did not help the children that took them, it actually made them more sick than average and the placebo doesnt matter because it wasnt the real vitamins. So the Wellness pharmaceuticals claim is false.

Answer 2

If you have to choose I'd go with

D. Wellness pharmaceutical company's claim is false; therefore, it can be concluded that the Wellness children's vitamin does not reduce the number of days a child is sick in a year.

There's really not enough information here to make that claim. We're not given any information on the standard deviations. About the strongest thing we can say with certainty at this point is that the very hardworking Elizabeth could not confirm Wellness Pharmaceutical Corp's claim. Elizabeth's data may prove the stronger statement; we'd have to see more of it to know.
