Math 533 Statistics Within this report I will discuss 3 variables and the comparison of 3 different pairs of variables. Location: The location data provided falls under three categories Suburban, Urban and Rural. This particular variable is qualitative thus certain numerical calculations could not be completed. The frequency for each category was determined and is depicted by the following table. Location Type | Frequency | Suburban | 15 | Urban | 21 | Rural | 14 | Total | 50 | Following calculating the frequency a pie chart was developed to determine which particular category had the highest percentage from the sample data provided.

Memorandum To: Marketing Department From: Andy Ali Date: 6/6/2014 Re: Comparison of 60614 and national profile WidgeCorp national sales meeting is approaching and I have been tasked to compare regional data (60614) to the national profile. Each profile contains four demographic reports (General Summary, Census Trend 1980 to 2000 Summary, Occupation and Employment Summary, and Income Summary) and the information will be drawn from these reports. General Summary The regional data shows that for the 2000 census 44.19% had an undergraduate degree and 33.99% of the population had a graduate degree. When this is compared to the national profile, the nation’s numbers show 15.54% had an undergraduate degree and 8.86% obtained a graduate degree.
So, 2000 = 30000/Square root of sample size. Solving for the Square root of sample size, we get Square root of sample size = 30000/2000 = 15. Taking its square, the sample size is found as 225. Chapter 9 Exercise 1 No it is not a good defense. If you choose 40 random employees from the corporation, the standard error would equal 6/Square root of 40 = .95 days.

Rector found that in 2004 low-skilled households received about $32,138 in benefits per household on average. Rector then found that these same households paid an average of $9,689 in taxes, resulting in the average low-skill household to collect $22,449 more in benefits than paid in taxes. Taking that $22,449, and multiplying it by the 17.7 million low-skill households, Rector concluded that the total deficit for such households was around $397 billion in 2004. “Over the next ten years the total cost of low-skill households to the taxpayer ... is likely to be at least $3.9 trillion” (York). That’s quite a bill to pay
