Answer:
Question 1: The most correct option is option D, which is 0.0133
Question 2: Her data is a random sample from the population of interest.
Explanation: For the first question;
Standard error I the error in the standard deviation. To calculate standard error the formula is used.
S.E = Sd/√n
S.E = standard error
Sd= standard deviation = 0.2
n = number of occurrence = 180
The proportion of the regular users of vitamin among the 180 people is the standard deviation between them.
Using equation above.
S.E = 0.20 ÷ √180 =
0.20 ÷ 13.42 = 0.0149
S.E is 0.0149, when compared to the options, the most correct option is 0.0133, because the question states the answer to be approximately to which of the option.
QUESTION2:
Her research will have much error, because she chooses the car to count. Therefore the research procedure has not satisfied the process that will produce an accurate result. Since she has choosed the street to be her population of interest, all the cars in the street should be counted.
This is not a randomized controlled research, so selection of cars to count is not necessary.
Probably engineering and probably airplanes

2% of $65000 = $1300 x 15 = $19,500 per year (which sucks).
Hope that helps.
Answer:
$500 million
Explanation:
Assets - Liabilities
= $750 - ($50+$100+$200+$100)
= $750 million - $450 million
=$300 million
Common stock = $40 million, Retained earnings = $160 miillon
Equity = $160 + $40 + $300 = $500 million
So, best estimate for the firm’s value of equity is $500 million.
