Answer:
A
Step-by-step explanation:
Answer:
p=2
Step-by-step explanation:
Use the slope formula
(p-(-1))/(6-9)=-1
(p+1)/-3=-1
p+1=3
p=2
Answer:
ŷ = 6.69X - 706.18 ; 270.56; B. The predicted value is not close to the actual diastolic reading.
Step-by-step explanation:
Given the data below :
Systolic reading(x) :
117
134
150
113
138
113
144
145
Diastolic (y) :
85
74
86
55
75
80
106
841
A) Find the regression equation, letting the systolic reading be the independent (x) variable:
Using the online regression calculator :
The regression equation obtained is ;
ŷ = 6.69X - 706.18
Where ;
ŷ = dependent variable
6.69 is the gradient or slope
-706.18 is the intercept, where the line crosses the y - axis.
X - the independent variable (Systolic reading)
B.) Find the best predicted diastolic pressure for a person with a systolic reading of 146 .
ŷ = 6.69X - 706.18
ŷ = 6.69(146) - 706.18
ŷ = 270.56
Is the predicted value close to 91.0
B. The predicted value is not close to the actual diastolic reading.
