(Need to show all your work to get full credit; no work, no credit) 1. For the given sample data below Construct a frequency distribution using six classes for a sample data that includes. Class Limits (5 pts), Class Boundaries (6 pts), Frequency (3 pts), Relative frequency (3 pts), Cumulative Frequency (3 pts), Midpoint x(5 pts), fxm (5 pts), fx (6 pts). a. b. For constructed grouped data find: mean (8 pts), mode for grouped data (2 pts), modal class (2 pts), the variance (10 pts), and the standard deviation (2 pts) c. Draw histogram and discuss the shape of a distribution (10 pts), frequency polygon (10 pts), ogive (10 pts), and pie chart for the following table (10 pt) NOTE: you MUST use 2.00 as a lower limit of the first class and do appropriate estimation for class width and in other computations. 4.6 6.6 3.7 5.9 4.1 6.3 2.9 4.2 5.0 4.7 5.4 2.4 4.6 6 4.2 5.3 5.0 2.6 5.4 5.73.8 4.17.96.2 3.03.3 5.0 4.1 4.8 7.2 643.0 3.5 5.37.73.9 4.0 5.4 5.6 3.4 4.0 3.6 5.5 Class Class Tally Frequency Relatve Cumulative Class Degrees Percent 01) Frequency Frequency MidpointExplanation / Answer
