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)
Answer:
Step-by-step explanation:
We want to find the equation of the line that goes through: !6,-10) and is perpendicular to the line
Let's simplify the equation of the line to get:
The slope of this line is -5.
The perpendicular to this line has a slope of
The equation going through (6,-10) is
We substitute to get;
Expand;
