Discuss how the dimension of set and setting and route of administration can change individuals’ experiences with alcohol. Also, make sure to mention how set and setting and route of administration will be likely to change the psychopharmacological effects that you listed.

Consider the Minimum Spanning Tree Problem on an undirected graph G=(V,E), with a cost ce ≥0 on each edge, where the costs may not all be different. If the costs are not all distinct, there can in general be many distinct minimum-cost solutions. Suppose we are given a spanning tree T ⊆ E with the guarantee that for every e ∈ T, e belongs to some minimum-cost spanning tree in G. Can we conclude that T itself must be a minimum-cost spanning tree in G? Give a proof or a counterexample with explanation.

Walsh Company manufactures and sells one product. The following information pertains to each of the company’s first two years of operations: Variable costs per unit: Manufacturing: Direct materials $ 28 Direct labor $ 14 Variable manufacturing overhead $ 2 Variable selling and administrative $ 1 Fixed costs per year: Fixed manufacturing overhead $ 320,000 Fixed selling and administrative expenses $ 50,000 During its first year of operations, Walsh produced 50,000 units and sold 40,000 units. During its second year of operations, it produced 40,000 units and sold 50,000 units. The selling price of the company’s product is $84 per unit. Required: 1. Assume the company uses variable costing: a. Compute the unit product cost for Year 1 and Year 2. b. Prepare an income statement for Year 1 and Year 2. 2. Assume the company uses absorption costing: a. Compute the unit product cost for Year 1 and Year 2. b. Prepare an income statement for Year 1 and Year 2. 3. Reconcile the difference between variable costing and absorption costing net operating income in Year 1.

An experiment was performed to determine the efficiency of a transformer. A coil is placed into another coil, and a steel bar is placed on the inside of both coils.

f (efficiency) = V1*N2 / V2*N1

Suppose we ignore the possibility of someone having miscounted the number of turns. Why might "1 turn" (or, perhaps, "1/2 turn") still make sense as an uncertainty on the number of turns?

What is a drying agent? When do you use it? What is the drying agent used in the lab? How much drying agent do you use? It has been suggested that drying agents can be collected after an experiment and the hydrated salt heated in an oven to drive off the water. The recycled drying agent can then be used again for another experiment. Is this a good idea? Give advantages and disadvantages of this proposal.

Please explain the origin and evolution of the Universe. Start from the Big bang, going through the critical moments for creations of particles, stars and the Solar system. Please try to include the following key words: (a) The Big Bang, (b) Inflation, (c) Spontaneous Symmetry Breaking, (d) Quarks and Leptons, (e) Baryogenesis, (f) Cosmic Microwave Background, (g) Dark matter, (h) Dark energy, (i) Formation of stars, (j) Fate of the Universe. Underline the key words. Do not forget to include the times from the Big bang for the important epochs.    

A new thermostat has been engineered for the frozen food cases in large supermarkets. Both the old and new thermostats hold temperatures at an average of 25°F. However, it is hoped that the new thermostat might be more dependable in the sense that it will hold temperatures closer to 25°F. One frozen food case was equipped with the new thermostat, and a random sample of 26 temperature readings gave a sample variance of 4.4. Another similar frozen food case was equipped with the old thermostat, and a random sample of 19 temperature readings gave a sample variance of 12.8. Test the claim that the population variance of the new thermostat temperature readings is smaller than that for the old thermostat. Use a 5% level of significance. How could your test conclusion relate to the question regarding the dependability of the temperature readings? (Let population 1 refer to data from the old thermostat.) (a) What is the level of significance? State the null and alternate hypotheses. H0: σ12 = σ22; H1: σ12 ≠ σ22 H0: σ12 > σ22; H1: σ12 = σ22 H0: σ12 = σ22; H1: σ12 > σ22 H0: σ12 = σ22; H1: σ12 < σ22 (b) Find the value of the sample F statistic. (Round your answer to two decimal places.) What are the degrees of freedom? dfN = dfD = What assumptions are you making about the original distribution? The populations follow independent chi-square distributions. We have random samples from each population. The populations follow independent normal distributions. The populations follow dependent normal distributions. We have random samples from each population. The populations follow independent normal distributions. We have random samples from each population. (c) Find or estimate the P-value of the sample test statistic. (Round your answer to four decimal places.) p-value > 0.100 0.050 < p-value < 0.100 0.025 < p-value < 0.050 0.010 < p-value < 0.025 0.001 < p-value < 0.010 p-value < 0.001 (d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? At the α = 0.05 level, we fail to reject the null hypothesis and conclude the data are not statistically significant. At the α = 0.05 level, we fail to reject the null hypothesis and conclude the data are statistically significant. At the α = 0.05 level, we reject the null hypothesis and conclude the data are not statistically significant. At the α = 0.05 level, we reject the null hypothesis and conclude the data are statistically significant. (e) Interpret your conclusion in the context of the application. Reject the null hypothesis, there is sufficient evidence that the population variance is smaller in the new thermostat temperature readings. Fail to reject the null hypothesis, there is insufficient evidence that the population variance is smaller in the new thermostat temperature readings. Reject the null hypothesis, there is insufficient evidence that the population variance is smaller in the new thermostat temperature readings. Fail to reject the null hypothesis, there is sufficient evidence that the population variance is smaller in the new thermostat temperature readings.

A test has an overall mean of 150 and a standard deviation of 8.50. The distribution of scores for each sub-set is often closely approximated by the normal curve. What percentage of students will score lower than 142 or better than 158?

Burnaby Ltd. is considering the acquisition of new production equipment. If purchased, the new equipment would cost $1,850,000. Installation and testing costs would be $35,000 and $25,000 respectively. Once operational, the equipment will cause an increase in working capital of $120,000. The new equipment is expected to generate increased annual sales of $720,000. Variable costs to operate the machine are estimated at 42% of sales and annual fixed costs would be lowered by $75,000. The equipment has an estimate 6 year life and a salvage value of $90,000. The company requires an 11% return on its investments. Ignore income taxes.
