Question

The human resources director of a large company recently asked her staff to conduct a study of the airline miles traveled by executives of the company during the most recent calendar year. The analyst assigned to the project randomly sampled

male executives and

female executives. Of particular interest to the HR director is whether males have greater variability in miles flown than females. The statistics available below were computed from the samples. Based on these data, what should the HR director conclude if an alpha level equal to

0.01

is used?

Males	Females
Mean Miles	73,262	66,888
St. Deviation Miles	2,568	1,539
Sample Size	25	25

Let sample 1 be males and sample 2 be females. What are the null and alternative hypotheses?

H0: σ21=σ22

HA: σ21≠σ22

H0: σ21≤σ22

HA: σ21>σ22

H0: σ21≥σ22

HA: σ21<σ22

H0: σ21≠σ22

HA: σ21=σ22

Determine the test statistic.

F=nothing

(Round to two decimal places as needed.)

Determine the critical value.

The critical F-value is

nothing.

(Round to two decimal places as needed.)

▼

Do not reject

Reject

the null hypothesis. There is

▼

insufficient

sufficient

evidence to conclude that males have greater variability in miles flown than females.
