3.Â Â Data were collected from CEO's in the consumer products and telecommunication industries. It is desired to compare the mean salaries between CEO's in the consumer products industry and CEO's in the telecommunications industry. The data were analyzed using the ASP software package.

HYPOTHESIS: MEAN X = MEAN Y

SAMPLES SELECTED FROM SALARY

X = Consumer Products

Y = Telecommunications

SAMPLE MEAN OF X = 1761

SAMPLE VARIANCE OF X = 3.97555E6

SAMPLE SIZE OF X = 21

SAMPLE MEAN OF Y = 1093.5

SAMPLE VARIANCE OF Y = 103255

SAMPLE SIZE OF Y = 21

MEAN X - MEAN Y = 667.5

test statistic = 1.47809

D. F. = 40

P-VALUE = 0.147626

P-VALUE/2 = 0.0738131

SD. ERROR = 451.597

Using alpha = .05, give the rejection region for a two-tailed test.

1) Reject H0 if t > 1.684.

2) Reject H0 if t > 1.684 or t 3) Reject H0 if t > 2.021 or t 4) Reject H0 if t > 2.021.
