Are medical students more motivated than law students? A randomly selected group of each were administered a survey of attitudes toward Life, which measures motivation for upward mobility. The scores are summarized below. The researchers suggest that there are occupational differences in mean testosterone level. Medical doctors and university professors are two of the occupational groups for which means and standard deviations are recorded and listed in the following table. Mean Group Sample size Medical = 15 Let us denote: • H₁: population mean testosterone among medical doctors, • H₂: population mean testosterone among university professors, • 0₁: population standard deviation of testosterone among medical doctors, • 0₂: population standard deviation of testosterone among university professors. Submit Answer Tries 0/5 Rejection region: We reject Ho at 2% level of significance if: Law If the processor interested to know whether the effects of the two preservatives on retarding spoilage are different, what are the appropriate hypotheses he should test?

Submit Answer Tries 0/3 1₂=5 Case 1: Assume that the population standard deviations are unequal, i.e. 0₁ 02. What is the standard error of the difference in sample mean [ (x)]-[(x)l2? i.e. s.e.([ (x)]-[ (x)]2) = [answer to 4 decimal places] The value of the test-statistic is: Answer to 3 decimal places. Submit Answer Tries 0/5 If a = 0.02, and the p-value is 0.3301, what will be your conclusion? Reject Ho Do not reject Ho. There is not enough information to conclude.
