Instructions

In this project, examine if the two independent groups of participants obtained significantly different scores on the dependent variable in the data set. Additionally, examine the normality of distribution of scores, and the homogeneity of variance across the two independent groups.

(1) Calculate a t-test for two independent samples using gender as the independent variable and IQ as the dependent variable.

(2) Discuss all results and provide an interpretation that includes:
correct use of descriptive statistics terminology;
analysis of the t-test, W test, and Levene's test as well any other common statistical terms;
conclusions related to the research questions and hypotheses;
and any limitations regarding those conclusions.

Use the Copy Object procedure to paste the SPSS output into a Word document. Be selective about the output that is chosen for presentation. Use only the output that supports your statements of discussion or interpretation.

Hypothesis testing for Kohl's average store sales in the east vs the west coast

The data is attached in eastwest.sav (need to have SPSS to open file)

The CEO of Kohl's is interested in understanding whether the average store sales for the stores in the east coast are significantly different from those in the west coast. The CEO suspects that since the company has been advertising more in the east coast, the east coast sales would be higher than those in the west coast. In order to test his hypothesis, the CEO asks his secretary to randomly pick 10 stores each in the east and west coasts and record their average monthly sales for the past year(in thousands of dollars).

State the appropriate hypothesis, run the appropriate test using SPSS and provide interpretation.
