Standard Deviation use in the Business World Abstract This paper evaluates the role of standard deviation in business. As part of the evaluation‚ a brief summary of five different peer reviewed papers has been presented. Topics such as‚ the purpose of the study‚ the research questions‚ the hypothesis of the study‚ and the main findings of the study for the five papers‚ have been summarized by each of the learning team members. Standard Deviation use in the Business World Standard Deviation is

9551/SQRT(300)‚1) = 0.0783 (c) A circuit contains three resistors wired in series. Each is rated at 6 ohms. Suppose‚ however‚ that the true resistance of each one is a normally distributed random variable with a mean of 6 ohms and a standard deviation of 0.3 ohm. What is the probability that the combined resistance will exceed 19 ohms? How "precise" would the manufacturing process have to be to make the probability less than 0.005 that the combined resistance of the circuit would exceed 19 ohms

Part 1 of 1 - | Question 1 of 10 | 1.0 Points | Consider the following scenario in answering questions 1 through 4. Results from previous studies showed 79% of all high school seniors from a certain city plan to attend college after graduation. A random sample of 200 high school seniors from this city reveals that 162 plan to attend college. Does this indicate that the percentage has increased from that of previous studies? Test at the 5% level of significance. State the null and alternative
