Question

Data Analysis Type I diabetes is common among children. Insulin shots are essential to maintain glycemic control and therefore avoid long-term consequences of diabetes. Those with high glycemic levels are said to be in poor control. However, an ongoing research question is whether maintaining glycemic control affects growth and development in childhood. For this study, a group of boys aged 9-15 were examined. Two regression models were run: a Using glycemic level ('glya1c") to predict boy's weight (wt kg b.

Explanation / Answer

27) There exist a positive relationship between glycemic level

and weight, as the co-efficient for glycemic level is positive.

Hence, Option (B) is the correct choice. (Ans).

28) Model 1 is not statistically significant, if we assume 5%

level of significance, since p-value = 0.06 > 0.05.

So the statement is False. (Ans).

29) Since the p-value of significance age is smaller than that

of glycemic level, age has the greatest effect on the outcome.

Hence, Option (B) is the correct choice. (Ans).

30) The given statement is True. (Ans).
