Nutrient deficiencies exist extensively among many members of the U.S population. More specifically, a research company claims that 90% of the U.S. population is Vitamin D deficient. A skeptical member of this research company decides to test this claim. He collects a random sample of 100 individuals from the U.S. population and determines that 84 individuals in the sample are Vitamin D deficient. Is there evidence that the true proportion of Vitamin D deficient individuals has decreased at the 0.01 significance level? What is the critical value for this hypothesis test? qnorm(0.005) = -2.576 O gnorm(0.01) = -2.326 O qt(0.01, df = 99) = -2.365 O qt(0.005, df = 99) = -2.626 %3D
