University of Phoenix Material Week Two Quiz 1. IN A GALLUP POLL OF 1,038 ADULTS, 540 SAID THAT SECOND-HAND SMOKE IS VERY HARMFUL. WHAT IS THE PERCENTAGE OF ADULTS WHO SAID SECOND-HAND SMOKE IS VERY HARMFUL? Show your work: Answer: 540/1038=0.5202312x100=52.023=52.02%= 52% 2. The first class in a relative frequency table is 50–59 and the corresponding relative frequency is 0.2.

Equally likely outcomes. C. Only two possible outcomes. D. A fixed number of trails. Ans: B 5) Which of the following is not a requirement of a probability distribution? A.
State the place value of the underlined digit in 6 953 742. A Hundreds C Ten thousands B Thousands D Hundred thousands ( 3. Round off 5 987 341 to the nearest hundred thousand. A 5.8 million C 6.0 million ( B 5.9 million D 6.1 million 4. Which of the following numbers, when rounded off to the nearest thousand, becomes 7 541 000?
Similarly the seventh row of results shows that for a five-year holding period and a “middle level” of risk aversion, the optimal allocation is 40.2% in the risk-free, 41.4% in T-Bonds, 3.2% in World Bonds, 9.0% in Large Stocks and 6.3% in Small Stocks. This portfolio’s expected return is 4.71% and its standard deviation is 2.38%. As the target date approaches the allocation shifts from the higher risk asset classes to the lower risk asset classes to a majority in the risk-free asset. 3. Look at the results in Table 1.
If the value of x is postnatal age of 30 hours, what is the value for Yˆ or SBP for neonates 1,001–1,500 grams? Show your calculations. 7. Compare the SBP readings you found in Questions 5 and 6. Explain the difference in these two readings.
18 7. If n = 38 – 28, which of the following is not a factor of n? z. 97 {. 65 |.
(True or False) (3.) Which of the following are not types of probability?1) Marginal probability2) Union probability3) Joint probability4) Conditional probability | (4.) In December of 1999, a research team at Ohio State University reported that the median allowance for U.S. teenagers is $50 per week, with a coefficient of skewness (as calculated in class) of 0.762. While some teenagers received no allowance, others reported receiving $200 per week. Based on this information, the mean allowance for U.S. teenagers is most likely.
So with that, I could generate a random number using the Excel RAND function that I designated r2 between 0 and 1. If 0 < r2< 0.2 then it takes 1 day 0.2< r2< 0.65 then it takes about 2 days 0.65 < r2 < 0.90 then it takes about 3 days 0.9 < r2 < 1 then it takes about 4 days 2. In Excel, use a suitable method for simulating the interval between successive breakdowns, according to the continuous distribution shown. With the probability increasing as time goes forward, the probability distribution of the random variable varies between the times of 0 to 6 weeks. In order to find an approximate result, it can be completed by the function F (x) = x/18 for 0 < x < 6 Therefore, the distribution function is F (x) = x-square divided by 36 for 0 < x < 6 If we set this equal to another random number r1 that is between 0 and then R1 = x-square divided by 36 which results to x = 6√ r1 3.
