of the Comparison Distribution (Aron, 2009). We want to determine if the null hypothesis is true, what is the situation that makes it so. We want to state that the population 1 is not the normal curve and population 2 is. If the null is true, they will both follow the normal curve. We will compare the two scores of the test to examine our results and to test the hypothesis and the null against one another. Step 3: Determine the Cutoff Sample Score on the Comparison Distribution at which the Null

plant. You ask your employees to measure the amount of soda there is in each bottle. 1. My first task is to calculate the mean, median, and standard deviation for the given ounces in the bottles. In order to complete this task, I transferred the data into an Excel workbook. I proceeded to the statistical functions to calculate the mean, median, and standard deviation. The results are defined in the following Excel image. 2. My next task is to construct a 95% confidence interval for the ounces

whose price is S In a short period of time of length Dt, the return on the stock (DS/S) is assumed to be normal with: mean m Dt standard deviation s Dt m is the annualized expected return and s is the annualized volatility. Fundamentals of Futures and Options Markets, 8th Ed, Ch 13, Copyright © John C. Hull 2013 2 Why can we say that? Assume that the Normal(m,s2) annual return is made up of the sum of n returns of shorter horizons (eg. monthly, weekly): m E ( ri )

Continuous Distributions Section 6.1 Uniform Distributions Formula Example Suppose a production line is set up to manufacture machine braces in lots of five per minute during a shift. When the lots are weighed, variation among the weights is detected, with lot weights ranging from 41 to 47 grams in a uniform distribution. Determine the probability that a lot weights between 42 and 45 grams Mean and Standard Deviation µ=(a+b)/2 σ=(b-a)/sqrt(12) Section 6.2 Normal Distribution

projects A, C, G, B, for a total of $875 million. 4. This question examines expected values, standard deviations, and risk measures for MICHTEC’s products with probabilities of .2, .5, and .3 for boom, recession, and normal growth. a. Expected annual revenues = $90(.2) + $75(.5) + $85(.3) = $77.175, or as this is expressed in millions of dollars, the expected annual revenues are $77,175,000. b. Standard deviation of annual revenues = [(90 – 77.175)2(.2) + (75 – 77.175)2(.5) + (85 –
