Imagine that a researcher performs an experiment examining the effects of nutrition on memory. each subject is randomly assigned to one of three groups: high-protein diet; high-fiber diet; standard diet (control). after a month on this diet, each subject undergoes a memory test. the experimenter finds that memory performance is somewhat better for the high-protein and high-fiber groups than for the control group, but the effect of nutrition is not statistically significant. thus, the experimenter accepts the null hypothesis. the experimenter hypothesizes that the effect was weak because the experiment was only 1 month long. a new experiment is then conducted that is identical to the first, except with 3 months on the diet. now a significant effect of nutrition is found. from these two experiments, the experimenter is justified in concluding that: [click all that are correct]a. nutrition impacts memory when people are on the diet for three monthsb. nutrition has a bigger impact on memory when people are on the diet for three months than when they are on the diet for one monthc. there is not sufficient evidence to conclude that nutrition impacts memory when people are on the diet for one monthd. nutrition has no impact on memory when people are on the diet for one month

Options A, B and C are correct.

Explanation:

A. Nutrition impacts memory when people are on the diet for three months

This option is correct because it was found that being on a high- protein or high-fiber diet for three months resulted in a significant improvement on memory performance tests. Note that "significant" here refers to statistical significance- which means the result is not due to random chance.

B. Nutrition has a bigger impact on memory when people are on the diet for three months than when they are on the diet for one month

This option is correct because when subjects were on a month long diet of either a standard diet, high- protein or high-fiber diet, it was found that memory performance is somewhat better for the high-protein and high-fiber groups than for the control group, but the effect of nutrition is not statistically significant. This means that the subjects on the high-protein and high-fiber groups did not conclusively do better on memory tests, and the result could be attributed to chance or other extraneous factors.

On the other hand, when subjects were on a high- protein or high-fiber diet for three months, it resulted in a significant improvement on memory performance tests- which means the result was not due to random chance.

C. There is not sufficient evidence to conclude that nutrition impacts memory when people are on the diet for one month

This option is correct because as stated above, it was found that memory performance is somewhat better for the high-protein and high-fiber groups than for the control group, but the effect of nutrition was not statistically significant- which means the results could be attributed to chance.

minerals contribute to our overall health because they your body grow, develop, and stay healthy. our bodies use minerals to us function throughout the day.tromhey us build strong bones, so we can do more things in life. with certain minerals, they can you maintain a normal heartbeat!

though, as as minerals are for us, they can also be very dangerous if one were to consume too many. if you were to take too much minerals, or even vitamins, you could experience nausea and diarrhea. all trace minerals can be very toxxic at high levels of consumption. taking too much of some minerals will result in hair loss! but this goes with almost everything in life, taking too much of something that is good, will eventually be bad for you.

my intake in minerals was normal. there really is no need to improve, i am healthy, and i am experiencing no nausea or diarrhea. i am as healthy as a bee. ☺ (sorry that i cannot you with the mineral intake)

what i have learned so far is that taking too much something can be very bad for you. taking too many minerals or vitamins, or anything healthy in general, can result in nausea and diarrhea, as well as hair loss. it would be a good idea to track what you put into your body, good or bad.
