A sample of 100 colored balls is selected from a large container of red balls and white balls-call it Container A.A second sample, this one of size 200, is selected from another container of red balls and white balls-call it Container B.The table below shows observed results from the two samples. You use a chi-square test to test the null hypothesis that the two containers contain the same proportion of red balls.In a table of "expected frequencies if the null hypothesis is true," what is the expected frequency that should be entered in the "Container A, Red Balls" cell?
A)48
B)96
C)52
D)104
