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 and CEOs in the consumer products industry. HYPOTHESIS: MEAN X = MEAN Y SAMPLES SELECTED FROM RETURN industry 1 (low tech) (NUMBER = 15) industry 3 (consumer (NUMBER = 15) products) X =industry1 Y =industry3 SAMPLE MEAN OF X =157.286 SAMPLE VARIANCE OF 1563.45 X- SAMPLE SIZE OF X = 14 SAMPLE MEAN OF Y =217.583 SAMPLE VARIANCE OF Y - 1601.54 SAMPLE SIZE OF Y12 MEAN X - MEAN Y = -60.2976 t4.23468 P-VALUE = 0.000290753 P-VALUE/2 = 0.000145377 SD. ERROR = 14.239 Using the printout above, find the test statistic necessary for testing whether the mean return-to-pay ratio of low tech CEO's exceeds the return-to-pay ratio of consumer product CEOs. 14.239 -60.2976 .000145377 -4.23468
