The samples must be randomly selected, depeldent, and each sample must have a normal distribution. O B. The samples must be randomly selected·independent, and each population must have a normal distribut on. O C. The samples must be randomly selected, dependent, and each population must have a nomail distribution. D. The samples must be randomly selected, independent, and each sample must have a normal distribution see s see s see s see s tion

Explanation / Answer

here there are assumption of two sample F test

1) samples are independent 2) the population from which the samples were obtained must be normal .

hence the option b.) is correct answer.

let x1,x2,......xn and y1,y2,y3 be independent and identically distributed samples from two population which each have a normal distribution. hence first ( A ) and ( C ) are not correct .

so, the sample must be randomly selected,independent , and each population must have a normal distribution hence the answer is ( B ).
