Answers to Week Two Homework Assignment ( Assignment 1) Chapter 7 Exercise 13 You should choose a sample size of 1000 people. Although the law of averages tells you that the average of 1000 people is very likely to be close to 60 inches -- and thus under 65 inches tall -- here you are winning a prize for each person over 65 inches tall, not when the average of all the people is over 65 inches tall. Having a larger sample will give you more chances at getting the prize. The law of averages pertains to the variability of a sample average -- not variability in individual data values themselves. Here, we are concerned with individual data values.
A firm’s value depends on the positive net income generated in the past. True False A firm’s value depends on the firm’s ability to generate positive cash flows now and in the future True False When determining the value of a firm, which of the following statements is true? • Inversters are risk neutral. Other things equal they prefer to pay more stocks that are less risky and have uncertain cash flows • Investers love risk. Other things equal they prefer to pay more for stocks that are more risky and have uncertain cash flows.
Practice Test 4 –Bus 2023 Directions: For each question find the answer that is the best solution provided. There is only one correct answer. 1. For a sample size of 30, changing from using the standard normal distribution to using the t distribution in a hypothesis test, a. will result in the rejection region being smaller b. will result in the rejection region being larger c. would have no effect on the rejection region d. Not enough information is given to answer this question. ANSWER: a -recall that all the t-values are larger than the z-values so it makes it more difficult to reject the null.
due = downpayment – total 10. Write a pseudocode statement that multiplies the variable subtotal by 0.15 and assigns the result to the variable totalfee. First you must make the variables real numbers. example.Dim subtotal As Double = 0 The statement asked for in the question will appear as totalfee = subtotal *
The HUD 242 program has the lowest interest rate of the 3 options but the main reason for suggesting this option is that compared to bank loans which sometimes treats hospital loans as junk; the HUD 242 gives the financing an investment grade of AA or AAA. Also if interest rates dropped in the future Elijah Heart Center could buy back the bonds at a lower interest
Both of these formulas were found on page 225 in Mathematics in Our World (Bluman, 2005). Problem #37 • This sequence is geometric • Ending balance is $814.45 STEPS/CALCULTATIONS YOU PERFORMED TO REACH THE ANSWER: To find the ending balance, the formula of An = a1(rn-1) will be used. The initial balance is $500, the interest is 5%, and the time span is 10 years. 5% will be listed as 1.05 as the initial balance is 100% plus 5% interest, so 105% is written 1.05. The number of terms is n=10, the first term is a1=525, the common ratio is r = 1.05.
Assignment #2 1) Improve the result from problem 4 of the previous assignment by showing that for every e> 0, no matter how small, given n real numbers x1,...,xn where each xi is a real number in the interval [0, 1], there exists an algorithm that runs in linear time and that will output a permutation of the numbers, say y1, ...., yn, such that ∑ ni=2 |yi - yi-1| < 1 + e. (Hint: use buckets of size smaller than 1/n; you might also need the solution to problem 3 from the first assignment!) 2) To evaluate FFT(a0,a1,a2,a3,a4,a5,a6,a7) we apply recursively FFT and obtain FFT( a0,a2,a4,a6) and FFT(a1,a3,a5,a7). Proceeding further with recursion, we obtain FFT(a0,a4) and FFT(a2,a6) as well as FFT(a1,a5) and FFT(a3,a7). Thus, from bottom up, FFT(a0,a1,a2,a3,a4,a5,a6,a7)
However if the behaviour is judged as immoral such as joining others in cheating there is less evidence of conformity as the costs are perceived as greater. Kohlberg found that individuals who are able to resist pressure to conform tend to be more morally advanced. Individuals can resist obedience if they have an ally who also opposes the authority figure. In Milgram’s study when the participant was given two allies that refused to continue giving shocks, only 10% of participants continued to the 450 volts shock level. Milgram claims that the presence of allies who resist an authority figure makes individuals more confident in their ability to do the same.
There is only a 1.28% chance that b = 0, which is better than the 10 percent level required by the marketing director. d. The exact level of significance of is 0.0927. There is a 9.27% chance that rivals’ spending on advertising does not affect Vanguard’s sales (i.e., b = 0), which is just barely better than the 10 percent level required by the marketing director. e. About 78 percent of the variation in sales remains unexplained. Find additional explanatory variables that have a significant affect on S. The manager might try adding the price of its detergent and the
The overall rating of Muscle Pharm Assault was 8.3 out of 10, which is quite reliable. Now of course it isn’t the highest rating there is but it is also cheaper than a lot of the other products there are. Most people said they enjoy the product and that it got them the adrenaline rush they desired. Only a few said they didn’t like it very well and that it wasn’t effective. In their defense, it may be true.
