The analytic scores on a standardized aptitude test are known to be normally distributed with mean u = 610 andstandard deviation o = 115. A normal curve with the parameters labeled is given below with a specific shaded region.Suppose the area under the normal curve to the left of X = 725 is 0.8413. What does this represent in context ofanalytic scores on a standardized aptitude test? Be sure to write one complete sentence, i.e., use college-level writing,in order to earn full credit.6107253. In an area of the Midwest, records were kept on the relationship between the rainfall (in inches) and the yield of wheat(bushels per acre). The data from the table are represented by a scatter plot and least-squares regression line. Whatis the relationship between yield of wheat and rainfall? What is the type of association?

Graphical representation refers to the use of charts and graphs to visually display, analyze, clarify, and interpret numerical data, functions, and other qualitative structures. Graphical representation refers to the use of intuitive charts to clearly visualize and simplify data sets. Data is ingested into graphical representation of data software and then represented by a variety of symbols, such as lines on a line chart, bars on a bar chart, or slices on a pie chart, from which users can gain greater insight than by numerical analysis alone. Representational graphics can quickly illustrate general behaviour and highlight phenomenons, anomalies, and relationships between data points that may otherwise be overlooked, and may contribute to predictions and better, data-driven decisions. The types of representational graphics used will depend on the type of data being explored. A histogram is a graphical representation that organizes a group of data points into user-specified ranges. It is similar in appearance to a bar graph. The histogram condenses a data series into an easily interpreted visual by taking many data points and grouping them into logical ranges or bins. Use a histogram when: The data are numerical You want to see the shape of the data’s distribution, especially when determining whether the output of a process is distributed approximately normally Analyzing whether a process can meet the customer’s requirements Analyzing what the output from a supplier’s process looks like Seeing whether a process change has occurred from one time period to another Determining whether the outputs of two or more processes are different You wish to communicate the distribution of data quickly and easily to othersFrom the given graph and data-set, we can deduce the following conclusion: Mode=100, Q1=97 Median= 92, Q3= 103 Mean = 99.9 Maximum=109 Minimum=92 Range=17 Geometric mean= 99.78931 Further the modal class is the bar with the highest frequency which is 94 to 101 ; Since our mode lies in this class interval our deductions are correct.
