CORRECT DETAILED ANSWERS (VERIFIED
ANSWERS) ALREADY GRADED A+ BRAND
NEW!!
Addition law - CORRECT ANSWER: useful when we want to know the probability that at least
one of two events occurs
P(A or B) = P(A) + P(B) - P(A and B)
Analytics - CORRECT ANSWER: the scientific process of transforming data into insight for
making better decisions
Bar chart - CORRECT ANSWER: a visual display of frequency; relative frequency & percent
frequency distributions
Binomial probability experiment - CORRECT ANSWER: 1. The experiment consists of a
sequence of n identical trials.
2. Two outcomes are possible on each trial; successor failure.
3. The probability of success (p) and the probability of failure (1-p) does not change from trial to
trial.
4. The trials are independent
Bivariate probability distribution - CORRECT ANSWER: A probability distribution involving
two random variables.
Categorical data - CORRECT ANSWER: use numeric or ordinal values of measurement of
categories
, Census - CORRECT ANSWER: a survey to collect data on the entire population
Chebyshev's Theorem - CORRECT ANSWER: Allows us to make statements about the
population of the data values that must be within a specified number of standard deviations from
the mean.At least 1 − 1/𝑧2 of the data values must be within z standard deviations of the mean (z
> 1)
Class limits - CORRECT ANSWER: each data observation must only belong to one class
Class midpoint - CORRECT ANSWER: value halfway between the lower and upper class limits
Classical method of assigning probabilities - CORRECT ANSWER: used when an experiment
has equally likely outcomes
Coefficient of variation - CORRECT ANSWER: measure of how large the standard deviation is
relative to the mean
Combination - CORRECT ANSWER: determining the number of ways x objects may be
selected from among n objects where order doesn't matter
Complement of event A - CORRECT ANSWER: all outcomes in which event A does not occur
Conditional probability - CORRECT ANSWER: the probability that one event happens given
that another event is already known to have happened; P(A|B)
Continuous random variable - CORRECT ANSWER: a random variable that may assume any
numerical value in an interval or collection of intervals
Continuous random variables - CORRECT ANSWER: any numerical value in an interval or
collection of intervals
