- "On average, which value is expected for the F-ratio if the null hypothesis is true?" F = 0 F = k 1 F = N k F = 1On average, what value is expected for the F-ratio if the null hypothesis is true? a. 0 c. k – 1 b. 1.00 d. N – k1. A researcher reports an F-ratio with df(between) = 3 and df(within) = 28. How many treatment conditions were compared in the experiment? If samples have an equal number of participants, how many are in each treatment? 2. A researcher obtains an F = 4.10 with df = 2, 14. Is this value sufficient to reject the null with α = .05? Is it sufficient enough to reject the null with α = .01?
- The tests of assumptions for yield gave values for Levene’s statistic and Shapiro-Wilk’s as 0.0562 and .00271, respectively. At a=0.05 , which statistical test is most appropriate to compare the yield among the nitrogen rates? a. Cochran’s Q B. Friedman’s C. Kruskal Wallis test . D. Anova F-testAssuming all other factors are held constant, if the df value for a two-tailed t-test with a = .05 were increased from df =6 to df = 20, what would happen to the critical values for t?a. Which of the two excel outputs above is the correct result of the data?b. What is the appropriate set of hypotheses for this test?c. From the given results above, which test is appropriate to test the significant difference between the heat-producing capacities of the coal from the mines?d. What is the t- critical value?e. What is the p-value?f. At α=0.05, what is the correct decision?
- On average, which value is expected for the F-ratio if the null hypothesis is false? a. F = 1 b. an F value between 0 and 1 c. an F value much greater than 1 d. F = 0The critical value of F for an alpha level of 0.05 and 2 and 12 degrees of freedom is 3.88. if the observed F value of 6.67 is greater than 3.88. what happens to the null hypothesis and explain your position?With α = .05, what is the critical t value for a one-tailed test with n = 25? t = 2.064 t = 1.711 t = 2.060 t = 2.708
- If the value for a t-test is t= 4, then what would the Fvalue be if an ANOVA was used instead of a t-test? a. 2 b. 8 c. 16 d. Cannot be determined based on the information givenAs a researcher using ANOVA, in order to reject the null hypothesis, we need the F ratio to be: a. -1 b. 1 c. 0 d. greater than 1 0A sample of n = 16 scores produces a t statistic of t = 2.00. If the sample is used to measure effect size with r2, what value will be obtained for r2?
