Answer:
90% confidence interval estimate of the mean depth of all the frame in the entire consignment is between a lower limit of 105.419 mm and an upper limit of 106.581 mm.
Explanation:
Confidence interval of mean is given as mean +/- margin of error (E)
mean = 106 mm
sample sd = 3.5mm
n is sample size = 100
degree of freedom = n-1 = 100-1 = 99
confidence level (C) = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
critical value (t) corresponding to 99 degrees of freedom and 10% significance level is 1.6602
E = t × sample sd/√n = 1.6602×3.5/√100 = 0.581 mm
Lower limit of mean = mean - E = 106 - 0.581 = 105.419 mm
Upper limit of mean = mean + E = 106 + 0.581 = 106.581 mm
90% confidence interval is (105.419 mm, 106.581 mm)

Answer: $3500
Explanation:
Preferred stock:
Number of shares = 1000
Par value = $50
4.5% cumulative
Common stock:
Number of shares = 10000
Par value = $10
Total first-year cash dividend paid = $1000
The cash dividend that must be paid to preferred stockholders in the second year before any dividend is paid to common stockholders is:
Preferred Stock dividend = 1000 × 0.045 × 50 = $2250
Unpaid dividend from year 1 = $2250 - $1000 = $1250
Year 2 dividend = $2250
Total dividend due in year 2 = $(1250 + 2250) = $3500
Percent markup based on the selling price: 28.1%
Explanation:
The cost of the TV for the seller was
Of this, the markup of this price was 39%. Therefore, the value of the markup (in dollars) with respect to the cost for the seller was
So, this was the markup relative to the cost for the seller.
The price paid by the purchaser instead is
Therefore, the percent markup based on the selling price (paid by the purchaser) is:
