What is hypothesis testing?

Hypothesis testing asks the question: Are two or more sets of data the same or different, statistically. In Six Sigma, hypothesis tests help identify differences between machines, formulas, raw materials, etc. and whether the differences are statistically significant or not.

Does Excel conduct a hypothesis test?

Using Excel, Chapter 8: Hypothesis Testing - One Sample Excel alone does not conduct complete hypothesis tests1. However, once you calculate the test statistic, Excel can get the critical values and the P-values needed to complete the test. The functions used to get critical values and P-values are demonstrated here.

How many black footed ferrets were there in 1987?

In 1987, 18 black-footed ferrets, the last known individuals of this species, were captured and brought into a captive breeding program in Wyoming. In 1989, the total ferret population, still in captivity, was 120 animals. These 120 animals in 1989 represented: A) rN, the geometric rate of growth of the population.

Does UV light degrade folate?

E) the potential for UV radiation (UV light) to degrade folate in the skin generally is higher, assuming that the amount and type of melanin in the skin does not change. F) the ability of human skin to produce vitamin D generally is lower, assuming that the amount and type of melanin in the skin does not change.
