What is 1/2 or 50%?
A and B and C
Mrs. Gatchell will present.
What is the letter used to define Pearson's Correlation Coefficient?
What is r?
What is the only number that is NOT a real Number?
What is imaginary number i = the square root of -1
When creating the Bell Curve, what are the 3 standard percentages described within the Bell curve?
What is 68%, 95%, and 99%?
Find the probability of rolling an odd, prime number on a fair six - sided die.
What is 2/6 or 1/3 or 33%
Shade the given area:
A and B and not C
Mrs. Gatchell will present.
What is the scale used to describe each possible value of r?
what is:
0 - 0.25 = no correlation to weak correlation
0.25 - 0.5 = weak correlation
0.5 - 0.75 = moderate correlation
0.75 - 1.0 = strong correlation
Name all of the subsets of Real Numbers.
What is; Rational Numbers, Irrational Numbers, Integers, and, Natural Numbers
The weights of men are normally distributed with a mean of 72 and standard deviation of 3.
Calculate the probability of picking a man chosen at random that weighs less than 67kg.
What is 0.0478 or 4.78%?
With a standard deck of cards, find the probability of drawing 2 Jacks in a row.
12/2652
Shade the given region:
(B U C) and A
Mrs. Gatchell will present on board
Given the table find the mean and standard deviation for the temperatures using your GDC.
***Mrs. Gatchell will hand out copy of the table
What is 19.2 degrees and 1.45 degrees?
The following is what type of number:
2pi / 4pi
What is a rational number?
The weights of men are normally distributed with a mean of 72 and standard deviation of 3.
It is known that 5% or men weigh more than w kg. Find w.
What is 76.9 kg?
You have a bag with 5 red marbles and 4 blue marbles.
Draw a tree diagram to represent drawing two marbles in a row without replacing for this situation.
Then find the probability of picking a red marble and then a blue marble.
What is 20/72 or 5/18?
Shade the given area:
(A U C) - B
Mrs. Gatchell will present.
Using the same table as before (300 question):
Find the line of best fit and Calculate Pearson's correlation Coefficient and comment on it.
What is y = 11.5 x - 100.3
and r = .94 which is a positive strong correlations.
solve for x and state what type of number your answer is:
x2 + 4 = 3
What is x = squareroot of -1 and it is an imaginary number.
The weights of men are normally distributed with a mean of 72 and standard deviation of 3.
for a man chosen at random,
the P( 72 - x < W < 72 + x) = .7
Find x.
What is 3.1?
You have a bag with 5 red marbles and 4 blue marbles.
Draw a tree diagram to represent drawing two marbles in a row without replacing for this situation.
Then find the probability of picking a red marble on the second draw.
What is 40/72 or 5/9?
Shade the given area:
A U (C - B)
Mrs. Gatchell will present.
Again using the same table and results from before:
Using the line of best fit, find how many bottles will be sold when the temp is 40 degrees.
You can not accurately use the line of best fit to estimate the numbers of bottles when your temperature is above (or below) any of the values in the original study.
