3 points Saved QUESTION5 Consider the experiment above where pigs were randomly assigned to one of two groups-one received a vitamin B12 supplement added to their food, the other group did not. The difference of means between the two groups (Vitamin B12 minus No vitamin B12) was 0.27 kg, and the 95% confidence interval was o.o7 to o.47 kg. According to these results, which of the following are plausible values for the true difference of means? (Tick as many as apply.) 0.40 kg o.o1 kg o.10kg 0.00kg 0.50 kg 0.27 kg

Explanation / Answer

Ans:

5,6)Plausible values of observed difference between means will be between 0.07 and 0.47.

So,correct options will be 0.10,0.27,0.40

7)second and third correct options are:

An absolute difference in means of 0.27 kg or more is unlikely if the true difference in mean weight gain between the vitamin B12 and the no vitamin B12 group is zero.

The true difference in mean weight gain(vitamin B12-no vitamin) is not zero.
