Answers

1
(Optional Calculator) What is the probability of "PP"?
.80
.70
.65
.5600
2
What must you not forget to do when using the Normal model?
Label lower/upper bounds, μ, and δ
Label each standard deviation
∎ and Δ
Label the necessary standard deviations
3
What equation can be used to test for independence?
P (A ∩ B) = 0
U = S(A)
P (B | A) = P (B)
P (A U B) = P (A) + P (B) - P (A ∩ B)
4
What is the Geometric model used for?
Predicting number of successes in n trials
Finding the expected value of a random variable
The Geometric model is obviously used in Geometry and not Statistics
Predicting when the first success will happen
5
Which of these has a Binomial model?
The number of females in a class of 30 students
The number of Jacks in a 5-card poker hand
The number of Kahoot questions until every student gets it right
The number of questions a on a Kahoot quiz
6
What's a random variable?
A numeric value which is based on the outcome of a random event
Any randomly generated integer used in simulations
A trait which is randomly selected to be altered in an experiment
A numeric value derived from data collected in real life
7
What equation can be used to test for disjoint events?
P (A ∩ B) = 0
P (B | A) = P (B)
P (A U B) = P (A) + P (B) - P (A ∩ B)
A ≠ B
8
Blast from the Past: How do you calculate the Far Upper Fence when creating boxplots?
Q1 - 1.5(IQR)
Q1 - 3(IQR)
Q3 + 1.5(IQR)
Q3 + 3(IQR)
9
Is the following setting an example of Bernoulli trials?
No. If a student gets an E, they are likely to get more E's.
Yes. All conditions are met.
No. There are 3 different possible outcomes, more than 2.
Yes. The trials aren't independent, but the 10% condition is met.
10
(Calculator) In 100 trials, what is the probability of getting 66 successes or more? p = .69
.7771
.6982
.3018
.2229
11
What grammatical error was made in the last question and group of answers?
"Which" was used instead of "that" in the triangle text box.
There was an apostrophe missing in "What's".
No grammatical errors were made, the question was created by Patrick Smith.
Commas were omitted where they should have been used
12
Is the following setting an example of Bernoulli trials?
No. The probability of a correct answer doesn't remain constant.
Yes. All conditions are met.
Yes. The trials aren't independent, but the 10% condition is met.
No. There are 4 different answers to each question, more than 2 outcomes.

How are discrete random variables different from continuous random variables?
Discrete random variables can only be used once
Discrete random variables have finite outcomes, continuous have infinite
Discrete random variables can be bounded on either side, unlike continuous
Discrete random variables have infinite outcomes, continuous have finite
