Question

please help

1. Consider the sample given below. Find the following information. 16 32 40 52 19 34 43 54 20 35 46 57 21 35 46 62 23 35 46 23 36 48 27 39 50 A. 1 B. Range = C. Midrange D. Mode = E. Class width if we wish to have 5 classes = F. How many numbers are strictly below 50? G. What percent of data are strictly below 50? H. Make a complete frequency distribution table starting with the minimum value: Class Class Frequency Cumulative Relative Percent Boundaries Midpoint Frequency Frequency Frequency Class Limits 1. What percent of data fall within 26 to 55, inclusive? J. Draw histogram, Ogive, Frequency Polygon, and Pie Chart

Answer 1

Solution-1:

(A)n=25

(B)range=max-min=62-16=46

(c)midrange=max+min/2

=(62+16)/2

=39

(d)mode is most repeating value

35 and 46 repeats 3 times

mode=35,36

(e)

class width=max-min/no of classes

=62-16/5

=46/5

=9.2

(f)

16 19 20 21 23 23 27 32 34 35 35 35 36 39 40 43 46 46 46 48

20 values are below 50

(g)20/25*100=80%

80 percent of data are strictly below 50
