A researcher would like to know which factors are most important to people whoare buying a new car. A sample of n = 200 customers between the ages of 20 and29 are asked to identify the most important factor in the decision process:

Performance, Reliability, or Style.

The researcher would like to know whetherthere is a difference between the factors identified by women compared to thoseidentified by men. The data are as follows:

	Performance	Reliability	Style	Totals
Male	21	33	26	80
Female	19	67	34	120
Totals	40	100	60	n=200

a) State the null and alternative hypothesis.

b) Determine the degrees of freedom and Chi square statistic when alpha = 0.05. (2 points)

c) Please see table below with the expected frequencies. Calculate the Chi Square statistic and describe how you would interpret it.

	Performance	Reliability	Style	Totals
Male	16	40	24	80
Female	24	60	36	120
Totals	40	100	60	n=200
