Which of the following best describes a relative class frequency? Oa lt is the number of observations that falls into a given class in a frequency distribution. Ob.It is the proportion of all observations that falls into a given class in a frequency distribution. Oc.It is the difference between the numerical lower and upper limit of a class of quantitative data. Od.It is the number of observations that...

A pair of dice are rolled 1,000 times with the following frequencies of outcomes: Sum 2 3 4 5 6 7 8 9 10 11 12 Frequency 10 30 50 70 110 150 170 140 120 80 70 Use these frequencies to calculate the approximate empirical probabilities and odds for the events a. The sum is less than 5 or greater than 8. b. The sum is even or exactly divisible by 3.
Benford's Law states the relative frequencies of the first digits in a dataset of naturally occurring random numbers will follow the trend seen in the table. Benford's law is used to detect fraud in accounting and other fields. We will consider three business called Business A, B, and C. We have their accounts payable database and have given the relative frequencies of the first digit for each item in their accounts payable. Relative Frequency First Benfords Business Business Business Digit...
1) Excel's _____________ can be used to construct a frequency distribution for quantitative data. a) COUNTIF function b) AVERAGE function c) FREQUENCEY function d) none of these answers is correct e) SUM function 2) Excel's ______________ can be used to construct a frequency distribution for qualitative data. a) Pivot Table report b) COUNTIF function C) chart wizard d) SUM function e) none of these answers is correct 3) The relative frequency of a class is computed by a) None of...
Problem 1: Game Spinner We will be comparing empirical (relative frequencies based on an observation of a real-life process) to theoretical (long-run relative frequency) probabilities. We will use StatCrunch to simulate this process using a board game spinner three times so that we can determine the total number of spaces moved in three turns. The board game spinner looks like the image below. The spinner is equally likely to land on any given section. f) Calculate the theoretical probability of...
