A geometric model counts the number of:

trials up to and including the first success

The value of a residual is:

(actual y-value of a data point)-(the predicted y-value)

A correlation of zero 0 means that:

there is no linear relationship between the variables

While using blocking you use randomization by:

randomly assigning treatments within your block

In the distribution below

1
A geometric model counts the number of:
trials up until the first success
successes in n trials
times I intend to cry during the AP Statistics exam
trials up to and including the first success
2
A type I error is
rejecting a true alternative
failing to reject a false null
rejecting a true null
failing to reject a true null
3
A scatter plot with linear data would cause a residual plot that
has a quadratic form
appears to have no pattern
has either a linear or non linear pattern
has a linear pattern
4
A correlation of 0.51 means that we know that the slope of the line of best fit would be
some negative number
some positive number
0.51
-0.51
5
The value of a residual is:
(the predicted y value)-(the actual y-value)
(actual y-value of a data point)-(the predicted y-value)
(actual x value)-(predicted x value)
(predicted x-value)-(actual x value)
6
A correlation of zero 0 means that:
there is no linear relationship between the variables
nothing
the data is skewed to the right
there is no relationship between the variables
7
SRS is
the only method of random sample
not random
a method of randomly sampling
8
True or false: It does not matter what I make my null and alternative hypothesis:
False
False
False
False
9
When you are calculating exact outcomes among a fixed number of trials you use a:
regression model
geometric model
probability distribution chart
binomial model
10
When events A and B have no effect on the probability of one anothers' occurrence, thy are:
dependent
independent
disjoint
mutually exclusive
11
While using blocking you use randomization by:
randomly deciding whether or not to use blocking
randomly assigning individuals to blocks
blocking cannot be used in a random sample
randomly assigning treatments within your block
12
Events that cannot occur simultaneously are known as:
independent
mutually exclusive
dependent
disjoint
13
In the distribution below
the mean is greater than the median
the mean and the median are the same
there is no way to tell if the mean or median is greater
the median is greater than the mean
14
When discussing a scatterplot I will discuss its
shape
spread
none of the above
center
15
When analyzing one variable data, you will discuss:
shape
center
spread
all of the above
