TABLE 10-1 Are Japanese managers more motivated than American managers? A randomly selected group of each were administered the Sarnoff Survey of Attitudes Toward Life (SSATL),which measures motivation for upward mobility.The SSATL scores are summarized below. -Referring to Table 10-1,give the null and alternative hypotheses to determine if the mean SSATL score of Japanese managers differs from the mean SSATL score of American managers. A)H₀ : μ_A - μ_J ≥ 0 versus H₁: μ_A - μ_J < 0 B)H₀ : μ_A- μ_J ≤ 0 versus H₁: μ_A - μ_J > 0 C)H₀ : μ_A- μ_J = 0 versus H₁: μ_A- μ_J ≠ 0 D)H₀ : - = 0 versus H₁ : - ≠ 0

The null and alternative hypotheses for this scenario should test for a difference in means between the two groups, which is represented by the symbol "μ". Therefore, options A, B, and D do not accurately represent the hypotheses. Option C correctly states the null hypothesis as the difference in means being equal to zero, and the alternative hypothesis as the difference in means being unequal to zero. This is the appropriate way to test if there is a significant difference between the mean SSATL scores of Japanese and American managers.
