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)
36/54 = x/100
54x = 100 * 36
54x = 3600
x = 3600 ÷ 54
x = 66.666666.... so 66.67
First put it into a proportion and then cross multiply. After that you divide both sides by 54 to get x alone which gives you 66.66666 which is rounded to 66.67
Answer: 66.67%

I'm also struggling with that too
Answer:
Area = 31.5 units^2
Step-by-step explanation:
7 x 3 = 21
Area of triangle is (height x base) / 2
(3 x 7) / 2 = 10.5
21 + 10.5 = 31.5
