In 2011, the institute of medicine (iom), a non-profit group affiliated with the select one us national academy of sciences, reviewed a study measuring bone quality 10 points and levels of vitamin-d in a random sample from bodies of 675 people who died in good health. 8.5% of the 82 bodies with low vitamin-d levels (below 50 nmol/l) had weak bones. comparatively, 1% of the 593 bodies with regular vitamin-d levels had weak bones. is a normal model a good fit for the sampling distribution? a. yes, there are close to equal numbers in each group. b. o yes, there are at least 10 people with weak bones and 10 people with strong bones in each group. c. o no, the groups are not the same size. d. o no, there are not at least 10 people with weak bones and 10 people with strong bones in each group.

B. Yes, there are at least 10 people with weak bones and 10 people with strong bones in each group.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size can be approximated to a normal distribution with mean and standard deviation

The correct answer is:

B. Yes, there are at least 10 people with weak bones and 10 people with strong bones in each group.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
