Reference no: EM1394265

One interesting aspect of the study descried in problem 10.64 is to assess changes in other parameters as a result of supplementation with vitamin A. One quantity of interest is the level of serum triglycerides. Researchers found that among 133 participants in the vitamin A group (males and females) who were in the normal range at baseline (<2.13 umol/L) 15 were above the upper limit of normal at each of their last 2 consecutive study visits. Similarly, among 138 participants in the trace group who were in the normal range at baseline (<2.13 umol/L), 2 were above the upper limit of normal at each of their last two consecutive study visits.

What test can be performed to compare the percentage of participants who developed abnormal triglyceride levels between the vitamin A and the trace group? Report a two-tailed p value.
