What is the critical value for a two-tailed F-Test with a=0.10, when the sample size from which the variance for the numerator was obtained was 10, and the sample size from which the denominator was obtained was 24?
In a certain city, 50 percent of the people consider themselves conservative (C), 25 percent consider themselves liberal (L), and 25 percent consider themselves to be independent (I).
The summation sign is usually represented by:
Get a test statistic and p -value. Interpret results at α = .01.
If F(x, y) is the value of the joint distribution function of the two continuous random variables X and Y a (x, y),
State the correct decision and give justification for your decision.
Assume that the significance level is a= 0.1. Use the given information to find the p-value and the critical value (s). With H1: p = with line through it 1/2 the test statistic is z= - 1.35
