Great Britain has experimented with different 40-hour work weeks to maximize production and minimize expenses. A factory tested a 5-day week (8 hour day), a 4-day week (10 hour day), and a 3 1/3 day week (12 hour day). The weekly production results follow: 8-hour day 87 76 75 90 72 10-hour day 75 82 90 80 73 12-hour day 95 76 87 82 65 Is there evidence of a difference among the mean weekly productivity levels for the three lengths of work-day? ☐ One sample Test for Proportions ☐ One sample Test for Means ☐ Two Sample Test for Means- independent ☐ Two Sample Test for Means - related ☐ Two Sample Test for Proportions ☐ Time Series Forecasting ☐ Correlation Analysis ☐ One-way Analysis of Variance ☐ Simple Linear Regression

Question 2 5 pts A formula to estimate the volume rate of flow, Q, flowing over a dam of length, B, is given by the equation $Q = 3.09BH^{\frac{3}{2}}$ where H is the depth of the water above the top of the dam (called the head). This formula gives Q in ft³/s when B and H are in feet. The constant, 3.09, is dimensionless and the equation is valid for any units of B and H. O True O False

2. The Baker's Supply Company produces flour in bulk for local bakeries. The flour can be produced at a fixed rate of 5,500 pounds per day. Annual demand for the flour is 1.25 million pounds per year. The fixed cost of setting up for a production run of the flour is $2,000, and the variable cost of production is $15.00 per pound. The company uses an annual interest rate of 20 percent to account for the cost of capital, and the costs of storage and handling of the flour. a. What is the optimal size of the production run for the flour? b. What proportion of each production cycle consists of uptime (i.e., time that the flour is being produced) and what proportion consists of downtime (i.e., time that the flour is not being produced)? c. Calculate the average annual cost of holding and the average annual cost of setup (calculate each separately) attributed to this item?

This question is about the Fibonacci sequence 1,1,2,3,5,8,13. . . Choose two successive Fibonacci numbers Fn and Fn+1 for n moderately large (numbers past the end of the part of the sequence shown above) and use the extended Euclidean algorithm to compute x and y such that gcd(Fn, Fn+1) = Fnx + Fn+1y. Then do this again for a larger n (for a larger pair of successive Fibonacci numbers). Describe any patterns that you notice (there will be some points reserved for actually describing some patterns, though most credit will reside in doing two EEA computations). You may be able to conjecture one or two theorems about the Fibonacci sequence after doing your calculations. Extra credit if you can give a formal proof by induction (or using the well-ordering principle) that for any n, gcd(Fn, Fn+1) = 1. There are ways of doing this by talking about the EEA computation, but it can be done directly in fairly simple ways as well (hint: one of the lemmas we used to prove that our algorithm for proving the Euclidean algorithm correct can be used)
