In a batch of 8,000 clock radios 9% are defective. A sample of 15 clock radios is randomly selected without replacement from the 8,000 and tested. The entire batch will be rejected if at least one of those tested is defective. What is the probability that the entire batch will be rejected?
In a basic aqueous solution, chloromethane undergoes a substitution reaction in which Cl- is replaced by OH-: CH3Cl(aq)+OH-(aq) <–> CH3OH(aq) + Cl-(aq)The equilibrium constant Kc is 1*10^16. Calculate the equilibrium concentrations of CH3Cl, CH3OH , OH- and Cl- in a solution prepared by mixing equal volumes of 0.1 M CH3Cl and 0.7 M NaOH . (Hint: In defining x, assume that the reaction goes 100% to completion, and then take account of a small amount of the reverse reaction.)
In a bar chart, the heights of the bars represent the frequencies in each class. A) True B) False The interquartile range is graphically presented in a A) Dot plot. B) Stem-and-leaf display. C) Box plot. D) Contingency table. Outliers are clearly presented in a A) Dot plot. B) Stem-and-leaf display. C) Box plot. D) Contingency table. A new car was put into production. It involved many assembly tasks. Each car was inspected at the end of the assembly line and the number of defects per unit was recorded. For the first 100 cars produced, there were 40 defective cars. Some of the cars had no defects; a few had one defect, and so on. The distribution of defects followed a Poisson distribution. Based on the first 100 produced, about how many out of every 1,000 cars assembled should have one or more defects? A) About 660 B) About 165 C) About 630 D) About 330 The Central Limit Theorem states that if the sample size, n, is sufficiently large, the sampling distribution of the means will be approximately normal, even when the population is skewed or uniform. A) True B) False Based on the central limit theorem, the sample mean can be used as a good estimator of the population mean, assuming that the size of the sample is sufficiently large. A) True B) False In multiple regression analysis, how is the degree of association between a set of independent variables and a dependent variable measured? A) Confidence intervals. B) Autocorrelation. C) Coefficient of multiple determination. D) Standard error of estimate.

In a changing global climate, how do you think jet streams would change and what effects might that have on society?

In a bank call center, it is determined over a one-year period that 30% of the outgoing calls are answered by a live person, as opposed to being unanswered or picked up on voice mail. The center makes over 200,000 outgoing calls per year. There is an operator at the center who places 25 outgoing calls in a one-hour period. What is the probability that this operator will get live answers on 7 or more calls?
In a certain region of space, the electric field, E, is constant in direction (say horizontally in the +x-direction), but its magnitude decreases from E1 = 533.3 N/C at x = 0 to E2 = 415.3 N/C at x = 47.1 ( NOT at at x = 30 m as shown in Fig. 22-27). Determine the charge within a cubical box of side L = 47.1 m, where the box is oriented so that four of its sides are parallel to the E-field lines.
In a certain economy, people save some part of their income in the financial sector and use the remaining part for consumption. The government decides to increase the tax rates for everyone in that economy. What effect will the tax increase have on savings and investment in the economy?
In a 750 word essay. Can you show how Jefferson’s theory of revolution (found in it shortest form in the Declaration of Independence) follows from John Locke’s theory of government? Could it follow from Hobbes’s theory of government? Under what circumstances?
