Use the rule method to describe the sample space S consisting of all points in the rst quadrant inside a circle of radius 3 with center at the origin.2.3 Which of the following events are equal? (a) A = {1,3}; (b) B = {x | x is a number on a die }; (c) C = {x | x2 4x +3=0 }; (d) D = {x | x is the number of heads when six coins are tossed}.

Chapter 2, Part One: Frequency Distributions, Histograms, and Related Topics 1. Frequency Distribution: paritions data into classes and assigns each class a frequency a. Frequency Tables: displays information in a frequency distribution, by listing each class along with its frequency b. Constructing a Frequency Table i. Decide on a number of classes between 5 and 15 ii. Calculate the class width 1. (Highest ValueLowest Value) / (# of Classes) a. (# of Classes) What was chosen in step one b. then, increase this value of class width to the next highest whole number. c. NOTICE: Even if it is an exact whole number, you will still increase it to the next highest. i. Example: 1. 6.0 7 iii. Find all lower class limits by starting with the lowest data value and successively adding the class width iv. Find all upper class limits by stopping at the whole number just below the lower limit of the next highe
