Question 10. Which of the following statements is false? The width of a confidence interval estimate of the population mean narrows when the value of the sample mean increases. The width of a confidence interval estimate of the population mean narrows when the sample size increases. The width of a confidence interval estimate of the population mean widens when the confidence level increases. Both "The width of a confidence interval estimate of the population mean narrows when the sample size increases" and "The width of a confidence interval estimate of the population mean widens when the confidence level increases." None of these

The marketing department of the Emirates Ship Co. has been allocated funds to increase their budget for an upcoming boat show. The department manager has asked the staff to determine which class of their products should benefit from additional advertising. The staff has determined that the pertinent states of nature are low, moderate, and high unemployment and have established the following payoff matrix. Assuming an optimistic (Maximax) slant in the staff report, which product category should be recommended? UNEMPLOYMENT CATEGORY Low Moderate High Probability 0.35 0.5 0.15 Fishing boat 35 25 10 Speed boat 55 25 15 Cabin 40 cruiser 25 25 Do nothing 0 0 0 0 Select one: O Cabin Cruiser O Do nothing O Fishing Boat O Speed Boat

For the following exercises, find the lengths of the functions of y over the given interval. If you cannot evaluate the integral exactly, use technology to approximate it. 181. y = 5 - 3x from y = 0 to y = 4 – 4

For this week's discussion, you are asked to generate a continuous and differentiable function f (2) with the following properties: • f(x) is decreasing at x = -6 • f(x) has a local minimum at x = -3 • f (x) has a local maximum at x = 3 Hints: • Use calculus! • Before specifying a function f (2), first determine requirements for its derivative f' (2). For example, one of the requirements is that f' (-3) = 0. • If you want to find a function g(x) such that g(-9) = 0 and g(8) = 0, then you could try g(x) = (x + 9) (x – 8). • If you have a possible function for f' (2), then use the techniques in Indefinite Integrals this Module to try a possible f (x). You can generate a plot of your function by clicking the plotting option (the page option with a "P" next to your function input). You may want to do this before clicking "How Did I Do?". Notice that the label "f(2) =" is already provided for you. Once you are ready to check your function, click "How Did I Do?" below (unlimited attempts). Please note that the bounds on the x-axis go from -6 to 6. f(x) = How Did I Do? Try Another

CLEARLY PLEASE Toluene is produced by hydroforming conversion of n-heptane in a Cr203@-A1203 catalyst medium. The operating conditions of the process are given on the flow chart. The solvent used in the process is recovered. CH3CH2CH2CH2CH2CH2CH2 - CH3CH3 + 4H2 Toluene production efficiency is 15% based on n-heptane fed into the process. The solvent ratio used in the extractor is 10 kg solvent / 1 kg toluene. According to this, a. Calculate how much heat must be added or removed to keep the reactor isothermal at 425 °C. b. What is the temperature of the n-heptane or solvent stream leaving the extractor. (The temperatures of the n- heptane and solvent streams can be considered the same.) но | 425 °C Cooler n-Heptane Superheater 425 °C 18°C 18 °C Catalytic Reactor HO Saturated Toluene vapour n-Heptane . 38c Solvent Heat Heat Extractor Still Exchanger Separator 18 °C 120 °C Solvent Solvent+Toluene
