A student collects data comparing the number of pages in a textbook
with its price. The student performs least squares regression analysis on
this data and finds the following least squares equation:
y = 0.216x + 19.85, where x is the number of pages in a textbook and Y
is its predicted price
An owner of a local restaurant observes that the longer a customer
waits to be seated, the less they spend meals. The owner obtains a
correlation coefficient of r=-0.715
Using just this information, what can be concluded?
a) an increase in wait time causes an increase in the amount customers
spend on meals
b) an increase in wait time is associated with an increase in the amount
customers spend on meals
,c) an increase in wait time is associated with a decreased in the amount
customers spend on meals
d) an increase in wait time causes a decrease in the amount customers
spend on meals
an increase in wait time is associated with a decrease in the amount
customers spend on meals
Using the given least squares equation, what is the estimated cost of a
textbook with 550 pages?
Round to the nearest cent.
a) $98.95
b) 118.80
c) $127.85
d) 138.65
$138.65
The following scatterplot depicts the amount of money spent at a
grocery store and the time spent in the store:
The regression equation y = 3.1x + 16.2 estimates the amount spent (in
dollars) based on the amount of time spent in a grocery store (in
minutes)
,Using the regression equation, what is the amount of money predicted
to be spent when a customer spends 15 minutes in the grocery store?
Round to the nearest whole number
a) $35
b) 53
c) 63
d) 70
$63
Solve for X:
X - 5/4 = 2/3
A) 3/12
B) 7/12
C) 10/12
D) 23/12
23/12
, If there are 2 tablespoons in 1 fluid ounce, how many tablespoons does
the following calculation yield?
4 fl. oz. - 1.5 tbsp.
a) 0.5 tbsp.
b) 1 tbsp.
c) 2.5 tbsp.
d) 6.5 tbsp.
6.5 tbsp
Solve for x.
x + 5/3 = 2/3
a) -3
b) -1
c) 1
d) 3
-1
Given the inequality:
2y + 6 > 20
a) y < 3
