A researcher tests whether Japanese managers are more motivated than American managers using the Sarnoff Survey of Attitudes Toward Life (SSATL), which measures motivation for upward mobility. A randomly selected group of each were administered The SSATL scores are summarized below.

Sample mean SSATL score

Sample Standard deviation

Sample size

American

78.5

31.1

210

Japanese

79.5

6.4

100

Suppose α = 0.01. Which of the following represents the correct conclusion?

Solutions

Expert Solution

To Test :-

H0 :-  

H1 :-  

Test Statistic :-


t = -1.6522


Test Criteria :-
Reject null hypothesis if


DF = 243


Result :- Fail to Reject Null Hypothesis


Decision based on P value
P - value = P ( t > 1.6522 ) = 0.0499
Reject null hypothesis if P value < level of significance
P - value = 0.0499 > 0.01 ,hence we fail to reject null hypothesis
Conclusion :- We Accept H0.

There is insufficient evidence to support the claim that Japanese managers are more motivated than American managers using the Sarnoff Survey of Attitudes Toward Life (SSATL).

3) A researcher is interested in studying whether or not baseball players are more superstitious than people in general. The population has an average score of 4.3 (SD = 1.9) on the superstitious scale. A sample of 36 baseball players scored an average of 4.7 on the superstitious scale. What does the distribution of sample means for this scenario consist of? What would we conclude and explain your decision using the distribution of sample means in your explanation.

A researcher tests whether the political affliction of individuals is related to or independent of whether they have positive views of the economy. The researcher records the political affiliations and economic viewpoints of 105 participants. (Affiliation: 1 = Democrat, 0 = Republican, Economy: 1 = Positive, 0 = Negative). Data: Affiliation: Democrat = 67, feel Economy is positive = 35, negative = 32. Affiliation: Republican = 20, feel Economy is positive = 20, negative = 18.
