Consider the following competing hypotheses and relevant summary statistics: (You may find it useful to reference the appropriate table: chi-square table or F table)

H0:2/12/2 1

HA:2/1 2/2< 1

Sample 1:s2/1= 647, and n1 = 26

Sample 2:s2/2= 1,422, and n2 = 23

a. Calculate the value of the test statistic. (Round intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.)
