Step-by-step explanation:
Given : Sample size : n= 1005
Number of adults stated that they were worried about having enough money to live comfortably in retirement = 531
Then the proportion of adults stated that they were worried about having enough money to live comfortably in retirement :
Significance level :
Critical value :
The confidence interval for population proportion is given by :-
Hence, the 90% confidence interval for the proportion of adults who are worried about having enough money to live comfortably in retirement = (0.504, 0.556)
Answer:
y=-5x+28 general form
slope point :y-(-7)=-5(x-7)
Step-by-step explanation:
definition :perpendicular slopes are negative reciprocals of each other
x-5y-2=0
y=1/5 x-2/5
slope of the perpendicular line =1/m=-1/(1/5)=-5
slope point :y-(-7)=-5(x-7)
find b :
y=-5x+b
-7=-5(7)+b
b=-7+35=28
y=-5x+28
y=1/5 x-2/5
