Question

1) To test whether the variance of a population is more than 74, the null hypothesis should be Ho: ?2 ≤ 74 .
a. True
b. False
c. Uncertain
Explain:

Answer 1

FALSE

claim : variance of a population is more than 74 ( ?2 > 74)

claim means alternative hypothesis or research hypothesis

Null Hypothesis is different to alternative hypothesis

alternative hypothesis is more , null hypothesis will be less or equal and vise verse

so

H0 :

Ha:   (Right tailed)

where

S² is sample variance

Hence the given statement is FALSE
