Break the problem down slowly
What info can we gather?
The woman says it rusts, so that is her main statement.
She uses her statement to make an assumption that because it rusts, it is not stainless steel.
Since she assumes it is not stainless steel, she thinks she did not get what she paid for, thus, her conclusion is that she should get a refund.
The best I could figure out with d is that the whole set is not stainless steel, so she should get a refund for the whole thing. The account says that some of the utensils have rusted, not all.
Hope this helps!
Using the z-distribution, it is found that a sample size of 1066 is required.
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which z is the z-score that has a p-value of .
The margin of error is:
From the previous study, the estimate is of 0.23, hence .
98% confidence level, hence, z is the value of Z that has a p-value of , so .
The sample size is <u>n for which M = 0.03</u>, hence:
Rounding up, a sample size of 1066 is required.

118+22=average length
which it would give you 140 in length :)
Use the formula for simple interest:
i = p*r*t
Then i = ($828.75)(0.065)(1.5)
= $80.80
6.5% must be converted to a decimal fraction: 0.065, and 18 months to years, specifically 1.5 years.
