When comparing the variables: RACE and XMARSEX, many conclusions arise. The contingency coefficient is: .070. This indicates a weak, positive relationship between the variables. This means that race has little impact on a person’s opinion about having sex with a person other than a spouse. The approximate sig is: .000.
$500 (= $25 ´ 20 radios not stolen due to hiring 1 guard) c. 4 Chapter 4 Applied Problem 1. a. The intercept a is expected to be positive because even if no advertising is undertaken, some sales are expected to occur. b is expected to have a positive sign since Vanguard's sales are positively related to its level of advertising expenditures. Vanguard's sales should be inversely related to its rivals' expenditures on advertising, so c is expected to be negative. b. a is the sales of Bright Side detergent when neither Vanguard nor its rivals advertise.
1. Does the ideal Gas Law do a reasonable job at predicting the behavior of the gas undergoing changes in temperature, pressure, and volume? Justify your answer with supporting evidence. Considering most gases don’t follow the ideal standards of the Ideal Gas Law, the law itself still provides reasonable calculations in predicting the behavior of gas. As long as we were able to identity two out of the three unknown variables, we could use the formula: PV=nRT to calculate the unknown value.
Question 1: Score 0/1 Your response Correct response P16-37 Find Missing Data for Profit Variance Analysis (L. O.4) Find the values of the missing items. Assume that the actual sales volume equals actual production volume. (There are no inventory level changes.) (Input all amounts as positive values. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance).
(b) Why might a driver be tempted not to use a seat belt “just on this trip”? Answer: (a) What is the probability of a fatal accident over a lifetime? 1/4,000,000 = 0.00000025 is the probability of a fatality, so therefore 0.99999975 relates to not having a fatality. N = 2, p = 0.00000025, a = fatal accident, b = no fatal accident Pa = 1 – Pb Pa = 1 – 0.00000025 Pa = 0.99999975 ^ 50000 = 0.987577799 Pa = 1 – 0.987577799 Pa = 0.012422201 or the probability of a fatal accident over a lifetime is 0.012422201 or 1.24%. One can assume independence; when we are assuming that none of our previous driving experiences had any fatal accidents does not make it any less likely that we will have an accident.
State the level of significance. c. Find the critical value (or values), and clearly show the rejection and nonrejection regions. d. Compute the test statistic. e. Decide whether you can reject Ho and accept Ha or not. f. Explain and interpret your conclusion in part e. What does this mean?
However, opponents argue the cameras only bring in revenue for cities and do not prevent accidents. The idea to implement these cameras is to prevent or reduce the number of accidents at intersections. According to the Insurance Institute for Highway Safety (I.I.H.S. ), “Red light cameras work and have reduced side impact accidents by an average of 24 percent and
1. Why aren’t risk analysis tools like Monte Carlo simulation and decision tree analysis more common in analyzing IT project risks? Risk analysis tools like Monte Carlo simulation and decision tree analysis are not more common in analyzing IT project risks because a Monte Carlo simulation is done by random generations while decision tree analysis is figured by chance. These random generations do not predict specific results. 2.
In spite of this, if one compare this price to the amount of CO2 depleted by petrol and diesel vehicles , it gives the idea that if all classic cars would be supplanted with electric ones, CO2 emissions would be diminished by about 500 times. Despite the fact that Electric cars are moderately new at the mass production scale and are not yet answering many demands of improved expense, range and charging pace. Each of which will be aided by enhancing
It is possible to reduce shit happening, from once a day to once a week, by using safer processes that result in the time period between near misses being larger. This improves safety in IT. The Incident Pyramid originated in 1931 when H.W. Heinrich described it in his book, Industrial Accident Prevention: A Scientific Approach. The Incident pyramid proposes that for every 300 unsafe acts there are 29 minor injuries and one major injury.
