Question

MATH 101 HW ASSIGNMENT Due Jan 25, 2019 Frequency Distributions A set of samples from a population measuring some characteristic of the group organized into a table Range Max. Value-Min. Value The distribution of data values are classified into several groups (or Classes) Class Width distance between the lower limit of one class and lower limit of the next higher class. Class Width (also) distance between upper limit of one class and the upper limit of next higher class cw-Range (# of Classes). Use the next highest integer (whole Number). For example, 525-) 6 1: FAT INTAKES (gms) (Problem 40 from textbook) Data Set (20 Values): Organize into 6 Classes: (16, 17, 24, 25, 29, 31, 32, 32, 33, 33, 33, 34, 36, 38, 39, 40, 40, 42, 54, 57) Make a Frequency Distribution Table for the above data set. (20 Values) What is the Range? What is the Mean Value (Average)? x What are the Lower and Upper Limits of Each Class? a) b) c) What is the Weighted Mean? (The Median is 33.) d) Sketch a Frequency Histogram for the above Data. For the following data set, create a frequency distribution table, find range, class width and the 2: upper and lower class limits for each class. The following data set has 30 values and should be organized into 5 classes. Next, sketch the Frequency Histogram for this data Find the weighted mean for this data by multiplying the midpoint for each class and multiplying the midpoint by the frequency (count) in each class ( 11, 12, 13, 17, 21, 23, 25, 28, 31, 33, 35, 37, 38, 39, 40, 42, 43, 44, 46, 47, 49, 51, 54, 57, 58, 59, 60, 61, 64, 68)
