Question

Determine the upper-tail critical value of F in each of the following one-tail tests for a claim that the variance of sample 1 is greater than the variance of sample 2 Click here to view page. Click here to view page 2 of the Ftable Click here to view page 3 of the F table 1of the F table. a.a -0.005, n 11, n2 13 b. ?=0.01. n1 = 11, n2 = 13 ilick here to view.nage4 ot the F table a. The critical value of F when ?= 0.005, n1-11, and n2-13 is 3.37 (Round to two decimal places as needed.) ]. b. The critical value of F when ?: 0.01, ?1 = 11. and n2 = 13 is 5.09 (Round to two decimal places as needed.)

Explanation / Answer

Ans:

a)n1=11,n2=13

df1=11-1=10

df2=13-1=12

Fcritical =FINV(0.005,10,12)=5.09

b)n1=11,n2=13

df1=11-1=10

df2=13-1=12

Fcritical =FINV(0.01,10,12)=4.30
