Answer: (141.1, 156.48)
Step-by-step explanation:
Given sample statistics : 


a) We know that the best point estimate of the population mean is the sample mean.
Therefore, the best point estimate of the mean weight of all women = 
b) The confidence interval for the population mean is given by :-
, where E is the margin of error.
Formula for Margin of error :-

Given : Significance level : 
Critical value : 
Margin of error : 
Now, the 90% confidence interval for the population mean will be :-

Hence, the 90% confidence interval estimate of the mean weight of all women= (141.1, 156.48)
Perpendicular means the two lines' slopes are negative reciprocal to each other. the slope of the given line is 1/3, therefore the slope of the perpendicular line is -3/1, which is -3
use the point-slope form: the given point is (4,1), so (y-1)=-3(x-4)
you can stop right here or you can write it into slope intercept form:
y-1=-3x+12
y=-3x+13
The answer is 1,2,4,6,8 because the circle has a circumference of 9
34 - 6 = 28
28 x 8 = 224
After making the 6 whole sheet of paper cards for her closest friends Aimi will have 28 pieces of paper left.
Since she wants to use 1/8 of a sheet per valentine (think of it as one piece of paper can make 8 valentines) you can do 28 pieces of paper multiplied by 8 which gives you 224 valentines.

Sorry I’m late.
Remember:
A STATISTICAL QUESTION has variable answers.
Ex: How many toys are in the U.S?
A NON-STATISTICAL QUESTIONS have only one answer
