Question: Explain how you would use Table V to find the
Explain how you would use Table V to find the two χ2-values that divide the area under a χ2-curve into a middle 0.95 area and two outside 0.025 areas. Find these two χ2-values for a χ2-curve with df = 14.
Answer to relevant QuestionsIt can be shown that the square of a standard normal variable has the chi-square distribution with one degree of freedom. Use that fact to show, for a chi-square curve with one degree of freedom, that χ2 α = z2 α/2. Distribution: 0.2, 0.1, 0.1, 0.3, 0.3; Observed frequencies: 29, 13, 5, 25, 28; Significance level = 0.10 We have provided a distribution and the observed frequencies of the values of a variable from a simple random sample ...Observing that the proportion of blue M&Ms in his bowl of candy appeared to be less than that of the other colors, R.
