We are interested in testing whether the variance of a population is significantly less than 1.44.The null hypothesis for this test is

A) H0: σ2 < 1.44.
B) H0: s2 ≥ 1.44.
C) H0: σ < 1.20.
D) H0: σ2 ≥ 1.44.

Variance

A statistical measurement of the spread between numbers in a data set, indicating how far each number in the set is from the mean.

Significantly Less

A statistical term used to indicate that one set of data is considerably lower than another with a level of statistical significance.

  • Formulate null hypotheses for testing variance and standard deviation claims.

Final Answer :
D
Explanation :
The null hypothesis is that the population variance is not significantly less than 1.44. Therefore, option D is the best choice, as it states that the population variance is greater than or equal to 1.44.
