Current Attempt in Progress At some instant the velocity components of an electron moving between two charged parallel plates are $v_x$=1.9×10$^5$ m/s and $v_y$=3.4×10$^3$ m/s. Suppose the electric field between the plates is uniform and given by $\vec{E} = (120 N/C)\vec{j}$. In unit-vector notation, what are (a) the electron's acceleration in that field and (b) the electron's velocity when its x coordinate has changed by 2.5 cm? (a) ($\boxed{\qquad}$$\vec{i}$ + $\boxed{\qquad}$$\vec{j}$. (b) ($\boxed{\qquad}$$\vec{i}$ + $\boxed{\qquad}$$\vec{j}$ Attempts: 0 of 5 used Submit Answer

Ouestion 11 (12 marks In an investigation of the effects of illumination level on task performance, the times that eight randomly selected people required to complete a task were recorded in each of two sets of conditions: low light level with a black background (A), and high light level with a white background (B). For each of the eight participants, the times (in seconds) taken to complete the task under the two conditions were recorded. These times, and the differences between them, are given in the table below. Person A B 1 2 29 21 8 3 32 23 9 4 26 20 6 5 20 20 0 6 41 25 16 7 25 16 9 8 27 25 18 23 5 Difference (A - B) 2 A Wilcoxon signed rank test is to be used to analyze these data (a)Write down the appropriate null and alternative hypotheses for the test. [2] (b) Calculate the value of the test statistic. [3] (c) Obtain the mean and variance of the normal distribution which may be used to approximate the null distribution of the test statistic. [2] (d) Use the approximate null distribution that you obtained in part (c) to test whether the combination of light level and background colour affects the time required to complete the task. You should include the details of your calculations and state your conclusions clearly. [4] (e) MINITAB is used to analyse the given data set and the exact p-value is 0.052. Suggest an explanation for the difference between this value and the one you calculated in part (d)? [1]

Special Order Analysis Holland Company produces a single product with a normal selling price of $75.00 per unit. The cost of producing and selling a single unit of this product at the company's normal activity level of 50,000 units per month is as follows: Direct materials....................................................................................$32.5 Direct labor......................................................................................7.20 Variable manufacturing overhead................................................................1.30 Fixed manufacturing overhead..................................................................20.90 Variable selling & administrative expense......................................................1.90 Fixed selling & administrative expense........................................................7.30 An order has been received from an overseas customer for 3,000 units to be delivered this month at a special discounted price. The variable selling and administrative expense would be $0.30 less per unit on this order than on normal sales. The order would have no effect on the company's normal sales and fixed manufacturing overhead costs would remain unchanged. However, fixed selling & administrative expense would increase by 5% if the order is accepted. Required: Suppose there is ample idle capacity to produce the units required by the overseas customer and the special discounted price on the special order is $65.60 per unit. By how much would this special order increase (decrease) the company's net operating income for the month?
