Does artistic ability determine which type of operating system a person prefers? Suppose that a market research company randomly selected =259 adults who used a desktop or laptop outside of the workplace (tablets and smartphones were excluded). The subjects were asked to identify the operating system of the desktop or laptop they used the most. The operating systems were classified as Windows, Mac OS, and Linux. There were no other operating systems reported in the survey.

The subjects were administered a test for creative imagery ability (TCIA), and based on the results, were classified as being exceptionally artistic or not. Exceptionally artistic was defined as being above the third quartile (the top 25 percent) of all people who took the TCIA. The table contains the results of the study.

	Windows	Mac OS	Linux	Total
Exceptional	46	4	3	53
Not exceptional	182	14	10	206
Total	228	18	13	259

The research company plans to conduct a chi-square test for independence to determe if artistic ability and operating system preference are dependent. Their null hypothesis is that they are independent. Assuming that artistic ability and operating system preference are independent, compute the expected number, of subjects who would prefer the Linux operating system and are rated as exceptional in terms of artistic ability.
