2. The engineering team at Manuel’s Manufacturing Inc. is planning to purchase an enterprise resource planning (ERP) system. The software and installation from Vendor A costs $380,000 initially and is expected to increase revenue $125,000 per year every year. The software and installation from Vendor B costs $280,000 and is expected to increase revenue $95,000 per year. Manuel’s uses a 4-year planning horizon and a 10% per year MARR.

a. What is the discounted payback period of each investment (do linear interpolation to answer)?

b. Based on DPBP, which ERP system should Manuel purchase?

Bianca has the following inventory, purchases, and sales data for the month of March. The physical inventory count on March 31 shows 500 units on hand. Inventory: March 1 200 units @ $4.00 $ 800 Purchases: March 10 500 units @ $4.50 2,250 March 20 400 units @ $4.75 1,900 March 30 300 units @ $5.00 1,500 Sales: March 15 500 units March 25 400 units Required: 1. Under a periodic inventory system, determine the cost of inventory on hand at March 31 and the cost of goods sold for March under (a) FIFO and (b) average-cost. 2. Under a perpetual inventory system, determine the cost of inventory on hand at March 31 and the cost of goods sold for March under (a) FIFO and (b) average-cost

A political scientist hypothesize that a political ad will increase attitudes about a particular issue. The scientist randomly asks 25 individuals walking by to see the ad and then take a quiz on the issue. The general public that knows little to nothing about the issue, on average, scores 50 on the quiz. The individuals that saw the ad scored an average of 47.55 with a variance of 28.73. What can the political scientist conclude with an α of 0.05?

a) What is the appropriate test statistic?
---Select--- na z-test one-sample t-test independent-samples t-test related-samples t-test

b)
Population:
---Select--- the ad individuals walking by general public the particular issue the political ad
Sample:
---Select--- the ad individuals walking by general public the particular issue the political ad

c) Compute the appropriate test statistic(s) to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
critical value =  ; test statistic =
Decision:  ---Select--- Reject H0 Fail to reject H0

d) If appropriate, compute the CI. If not appropriate, input "na" for both spaces below.
[  ,  ]

e) Compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
d =  ;   ---Select--- na trivial effect small effect medium effect large effect
r² =  ;   ---Select--- na trivial effect small effect medium effect large effect

f) Make an interpretation based on the results.

Individuals that watched the political ad scored significantly higher on the quiz than the general public.Individuals that watched the political ad scored significantly lower on the quiz than the general public.    Individuals that watched the political ad did not score significantly different on the quiz than the general public.

A 0.4485 g sample of pewter, containing tin, lead, copper, and zinc, was dissolved in acid. Tin was precipitated as SnO2·4H2O and removed by filtration. The resulting filtrate and washings were diluted to a total volume of 250.0 mL. A 15.00 mL aliquot of this solution was buffered, and titration of the lead, copper, and zinc in solution required 34.07 mL of 0.001534 M EDTA. Thiosulfate was used to mask the copper in a second 20.00 mL aliquot. Titration of the lead and zinc in this aliquot required 34.56 mL of the EDTA solution. Finally, cyanide was used to mask the copper and the zinc in a third 25.00 mL aliquot. Titration of the lead in this aliquot required 25.76 mL of the EDTA solution. Determine the percent composition by mass of each metal in the pewter sample.
