Data was collected from CEOs of companies within both the low-tech industry and the consumer products industry. The following printout compares the mean return-to-pay ratios between CEOs in the low-tech industry with CEOs in the consumer products industry.

       HYPOTHESIS: MEAN X = MEAN Y

SAMPLES SELECTED FROM RETURN
industry 1(low tech)(NUMBER = 15)
industry 3(consumer products)(NUMBER = 15)
___________________________________________________

X = industry1
Y = industry3
SAMPLE MEAN OF X =157.286
SAMPLE VARIANCE OF X =1563.45
SAMPLE SIZE OF X =14
SAMPLE MEAN OF Y =217.583
SAMPLE VARIANCE OF Y =1601.54
SAMPLE SIZE OF Y =12
MEAN X - MEAN Y =-60.2976
t =-4.23468
P-VALUE =0.000290753
P-VALUE/2 =0.000145377
SD. ERROR =14.239

Using the printout, which of the following assumptions is not necessary for the test to be valid?
◦ The population means are equal.
◦ The population variances are equal.
◦ Both populations have approximately normal distributions.
◦ The samples were randomly and independently selected.
