Question 1:
We want to evaluate the impact on the monetary economy for a company of two types of strategy (competitive strategy, cooperative strategy) adopted by buyers.
Competitive strategy: strategy characterized by firm behavior aimed at obtaining concessions from the buyer.
Cooperative strategy: a strategy based on a problem-solving negotiating attitude, with a high level of trust and cooperation.
A random sample of 17 buyers took part in a negotiation experiment in which 9 buyers adopted the competitive strategy, and the other 8 the cooperative strategy. The savings obtained for each group of buyers are presented in the pdf that i sent:
For this problem, we assume that the samples are random and come from two normal populations of unknown but equal variances.
According to the theory, the average saving of buyers adopting a competitive strategy will be lower than that of buyers adopting a cooperative strategy.
a) Specify the population identifications and the hypotheses H0 and H1 that we want to submit to the test. Also specify whether the research hypothesis is the null hypothesis or the counter-hypothesis.
b) Specify the conditions for applying the test.
c) Which statistic is suitable for carrying out this test (Z, t, chi-square, Fisher, etc.)? Explain?
d) According to H1 and at the threshold a= 0.01, what is the critical value?
e) What decision rule should be adopted?
