Find the appropriate critical F-value for each of the following using the F-distribution table.
a.
D 1=12,
D2=20,
α=0.025
b.
D1=20,
D2=15,
α=0.025
c.
D 1=12,
D2=20,
α=0.01
Solution :
a)
D 1=12,
D2=20,
α=0.025
Critical F-value = F12,20,0.025 = 2.676
b)
D1=20,
D2=15,
α=0.025
Critical F-value = F20,15,0.025 = 2.756
c)
D 1=12,
D2=20,
α=0.01
Critical F-value = F12,20,0.01 = 3.23

Use Critical Values for the Student's t Distribution Table to find the critical value or values for the following values of the significance level a, sample size n, and alternate hypothesis H. Part 1 of 4 When a=0.01, n=11, and H: > Ho- t = 2.764 Part: 1/4 Part 2 of 4 When a = 0.025, n = 10, and H: <HO =
Google Sheets can be used to find the critical value for an F distribution for a given significance level. For example, to find the critical value (the value above which you would reject the null hypothesis) for α=0.05α=0.05 with dfbetween=3dfbetween=3 and dfwithin=44dfwithin=44, enter =FINV(0.05,3,44) Enter this into Google Sheets to confirm you obtain the value 2.816. You conduct a one-factor ANOVA with 7 groups and 5 subjects in each group (a balanced design). Use Google Sheets to find the critical...
12. For each of the following situations, find the critical value for z a) Hoff 0.05 vs. HA:p > 0.05 at α 0.05. b) Ho:p 0.6 vs. HAip 0.6 at α 0.01. c) Ho:p 0.5 vs. HAP < 0.5 at α 0.01; n 500. d) Ho: 0.2 vs. HA:p < 0.2 at α 0.01 .
The Student's t distribution table gives critical values for the Student's t distribution. Use an appropriate d.f. as the row header. For a right-tailed test, the column header is the value of α found in the one-tail area row. For a left-tailed test, the column header is the value of α found in the one-tail area row, but you must change the sign of the critical value t to −t. For a two-tailed test, the column header is the value...
Use Critical Values for the Student's t Distribution Table to find the critical value or values for the following values of the significance level a, sample size n, and alternate hypothesis H. Part: 0 / 4 Part 1 of 4 When a 0.01, n = 11, and H:> HO
Find the following F distribution values from Table 4 of Appendix B (to 2 decimals each). a. F os with degrees of freedom 5 and 10 b. F.o2s with degrees of freedom 20 and 15 C. F.o1 with degrees of freedom 8 and 12 d. F.10 with degrees of freedom 10 and 20
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.
