What is the level of significance? State the Null and alternative hypotheses. Will you use a left field, right tailed, or two tailed test? Identify the sampling distribution you were used and explain the rationale for your choice what is the value of the sample test statistic? Find or estimate the P value. Will you reject or fail to reject the null hypothesis? State your conclusion in the context of the application. How productive are employees? One way to answer this question is to study in your company profit per employee. X subscribe to one represent annual profit per employee in computer stores in St. Louis. A random sample of n subscript one equals 11 Computer stores gave a sample mean of X bar subscript one equals $25.2 thousand profit per employee with sample standard deviation S subscript one equals $8.4 thousand. Another random sample of n subscript 2 Equals nine building supply stores in St. Louis gave a sample mean X bar subscript two equals $19.9 thousand per employee with sample standard deviation S subscribe to equals $7.6 thousand. Assume that X bar subscript one and Equals nine building supply stores in St. Louis gave a sample mean X bar subscript two equals $19.9 thousand per employee with sample standard deviation S subscribe to equals $7.6 thousand. Assume that X bar subscript one and x bar subscript two are normally distributed.Does this indicate that in St. Louis, computer stores tend to have higher mean profits per employee? Use level significance equals .01.
