8) The F value for 6 degrees of freedom for the numerator, 24 degrees of freedom for the denominator, and a 0.05 area in the right tail is: a. 2.60 Ob.2.51 O c. 2.78 O d. Cannot answer from given information. QUESTION 9 9) A researcher wishes to see whether there is any difference in the weight gains of athletes following one of three special diets. Athletes are randomly assigned to three groups and placed on the diet for six...
df (numerator) = 3, df (denominator) 18, c 0.05 Fcrit (Use two decimal places.) - df (numerator) = 4, df (denominator) 38, a 0.05 Fcrit (Use two decimal places.) = df (numerator) = 4, df (denominator) 38, o 0.01 (Use two decimal places.) Fcrit What happens to Fcrit as the degrees of freedom increase and alpha is held constant? Fcrit does not change Farit increases. Farit decreases What happens to Fcrit When the degrees of freedom are held constant and...
Finding F critical for Variances Use the F-distribution to find the degrees of freedon for the numerator (d.f.N.), the degrees of freedom for the Denominator (d.f.D.) and the critical F-value Use the closest value when looking up the d.f.N. and d.f.D. in the tables. Test alpha α Sample 1 Sample 2 d.f.N. d.f.D. F critical Right 0.01 s12=37 n1=14 s22=89 n2=25 Two-tailed 0.10 s12=164 n1=21 s22=53 n2=17 Right 0.05 s12=92.8 n1=11 s22=43.6 n2=11
What is the F value associated with α = 0.05, numerator degrees of freedom (df1) equal to 4, and denominator degrees of freedom (df2) equal to 8? a. 3.63 b. 6 c. 3.84 d. 0.6
please help with question 4 degrees of freedom for either the numerator or denominator of F, use the closest smaller number. For instance, if the degrees of freedom for the denominator were df, 23 you would use the critical value for df = 20 (2,3) 4. Chapter 10, Problem 10.10 If the degrees of freedom for I do not appear in Table A.2 use the closest smaller degrees of freedom to determine the critical value of t. For instance, if...
Let t be a t-random variable. P(t>a) 0.025 and 12 degrees of freedom. Find a. P(t < a) 0.05 and 21 degrees of freedom. Find a. P(-a < t<a) = 0.95 and 27 degrees of freedom. Find a. For 15 degrees of freedom, find P(t < 1.753) For 22 degrees of freedom, find P(-2.074 < t < 2.074). Use Excel function =t.dist to find P(t<-2.86) with df 25 Use Excel function =t.dist.rt to find P(t > 1.33) with df 29...
Find the critical value for a right-tailed test with a = 0.025, degrees of freedom in the numerator= 12, and degrees of freedom in the denominator = 25. What is the critical value? (Round to the nearest hundredth as needed.)
Between Y 39.62 8.70 Total use the tool to find the critical F value, set both the numerator F distnbution. Move the orange line until the area in the tail is equivalent of freedom; this will show you the appropriate to the alpha level you are investigating. here to s F distribution. Move the orange line until the area in the tail is equivalent to the alpha level you are investigating. 3000 At the a - .os level of significance,...
Artan probability Entries in the table give F. values, where a is the area or probability in the upper tail of the F distribution. For example, with 4 numerator degrees of freedom, 8 denominator degrees of freedom, and a .05 area in the upper tail, Fos = 3.84. Find the following F distribution values from Table 4 of Appendix B. a. F.05 with degrees of freedom 5 and 10 b. F.025 with degrees of freedom 20 and 15 c. F.01...
