The Food and Nutrition Board of the Institute of Medicine working in cooperation with scientists from Canada have used scientific data to answer this question for a variety of vitamins and minerals.47 Their methodology assumes that needs, or requirements, follow a distribution. They have produced guidelines called dietary reference intakes for different gender-by-age combinations. For vitamin C, there are three dietary reference intakes: the estimated average requirement (EAR),which is the mean of the requirement distribution; the recommended dietary allowance (RDA),which is the intake that would be sufficient for 97% to 98% of the population; and the tolerable upper level (UL), the intake that is unlikely to pose health risks. For women aged 19 to 30 years, the EAR is 60 milligrams per day (mg/d), the RDA is 75 mg/d, and the UL is 2000 mg/d. (a) The researchers assumed that the distribution of requirements for vitamin C is Normal. The EAR gives the mean. From the definition of the…

The human resource manager of company wanted to know how the Performance of the workers depend on Environment, Value, Motivation and Remuneration. He selected 100 workers randomly and used a questionnaire to obtain the scores on their perceived Environment, Value, Motivation and Remuneration. The final score on each variable ranged from 1 to 10, where a high score is supposed to be associated with high performance. In the study, the key performance index (KPI) was used as the indicator of worker performance. The following are some of the outputs from SPSS. a) Write the linear regression equation of Performance upon Environment, Value, Motivation and Remuneration. b) Interpret the coefficients for Environment in the regression equation in (a). c) Test if there is a problem of multicollinearity
