EXERCISE 11 1. What demographic variables were measured at least at the interval level of measurement? Age (yrs)‚ Income (annual)($)‚ Length of labor (hrs)‚ Return to work (wks)‚ and Number of hours working per week were measured at least at the interval level of measurement 2. What statistics were used to describe the length of labor in this study? Were these appropriate? The variable length of labor were used to describe by ratio data that can be described by using mean‚ range‚ and standard

smallest to largest. Once I had done this I split both sets of my data up into the upper quartile‚ lower quartile and I found the median which was my 20th bit of data. After I had done this I then worked out my interquartile range by taking my lower quartile away from my upper quartile which gave me the interquartile range. I got the upper and lower quartile and median by ordering my data and then splitting it up into quarters. I then recorded my highest and lowest values because this gives me the

of cups/lids until all the cups/lids are paired. The overall time complexity is O(n log n) (Worst case: O(n2 )). Problem 3 20 Pts Answer: In this problem we are more interested in finding the median instead of the minimum/maximum element. The ⌊ n ⌋th element in a min/max heap is not the median. 2 In this case‚ we should develop a new type of heap to adapt this problem. Problem 3 2 The solution is to use two heaps: a min heap and a max heap. Suppose the total number of elements is

For every 100 females age 18 and over‚ there were 89.70 males. The median income for a household in the county was $43‚337‚ and the median income for a family was $53‚223. Males had a median income of $35‚939 versus $30‚683 for females. The per capita income for the county was $23‚156. About 9.80% of families

Once the red blood cell returns to the heart‚ it enters through the vana cava (vein) returning the deoxygenated blood from the upper part and the lower parts of the body to the heart. This large veins lead into the right atrium where the pumping heart forces the red blood cells through the tricuspid valve into the right ventricle. The valve stops blood from flowing backwards into the right

What is the job of the Circulatory System? The Circulatory System is responsible for transporting materials throughout the entire body. It transports nutrients‚ water‚ and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce. It is an amazing highway that travels through your entire body connecting all your body cells. Parts of the Circulatory System The circulatory System is divided into three major parts: 1.

Opening Weekend Gross Sales After calculating several central tendency measures (mean‚ median‚ and mode)‚ one can create a histogram and see the opening weekend gross sales are heavily skewed to the right. The median opening gross sales of 0.39‚ indicating 50% of the opening gross sales values were less than 0.39 and 50% were greater than 0.39‚ would be a more appropriate central tendency measure than
