D. the proportion in a survey that favor a certain opinion. 5. Fill in the blank: Central Limit Theorem allows us to compute probabilities on ___________ using the standard Normal table provided the sample size of the random sample is sufficiently large. A. x B. μ C. s D. sample measurements. 6.
5. If find f(g(x)). 6. Write the slope-intercept form of the equation of the line containing the points (4,7) and 7. Write the equation of the line perpendicular to , passing through the point (6,1).
Chapter 3 Risk Identification and Measurement I. Multiple Choice 1. A listing of a random variable’s possible outcomes and the respective probabilities of those outcomes is called the: a. expected value b. standard deviation c. probability distribution d. correlation Answer: c Type: K 2. Multiplying each possible outcome of a random variable by its probability of occurrence, and then adding up these results will be equal to the random variable’s: a. expected value b. standard deviation c. probability distribution d. correlation Answer: a Type: K 3. The graph above depicts the probability distributions for risks A and B.
3.) First, let’s find the slope from point A to point B. m=0-3/-3-0. This equals -3/-3, which reduces to positive 1. Now, we can use point-slope form. I will use point B and it would look like this: y-(0)=1(x-(-3)).
4. The data in the scatter plot can be modeled using a function of the form T= a x b^t +c Find values of a, b, and c that produce a reasonable model. A=.048332 B= -3.8573 C=
In order to understand what an integral is or how to take an integral one must understand the concept of a derivative or differentiation. A derivative is the instantaneous rate of change of y with respect to x. When a derivative is taken what we find is the slope of the tangent line to a graph at the point P. We can approximate the slope by drawing a line through the point P and another point nearby, and then finding the slope of that line, called a secant line. b-ya-x=∆y∆x=fx+∆x-f(x)∆x (Kline, 1967) Then we must choose a random interval to be ∆x. How does the size of ∆x affect our estimate of the slope of the tangent line?
Is it reasonable to assume that the weights are normally distributed? Why? b) Find the mean and standard deviation of your sample. c) Is there a high probability that the mean and standard deviation of your sample are consistent with those found in previous studies? Explain your reasoning.
The first class in a relative frequency table is 50–59 and the corresponding relative frequency is 0.2. What does the 0.2 value indicate? Answer: 0.2 is equal to 1/5 or 20%, 0.2 indicates 20% of the data values are in this particular interval. 3. When you add the values 3, 5, 8, 12, and 20 and then divide by the number of values, the result is 9.6.
Write a pseudocode statement that declares the variable cost so it can hold real numbers. * Dim cost1 As Double = 0 6. Write a pseudocode statement that declares the variable total so it can hold integers. Initialize the variable with the value 0. * Dim cost1 As Integer = 0 7.
Provide a rationale for your answer. 4. Yˆ represents the predicted value of y calculated using the equation Yˆ = a + bx. In Figure 2, the formula for SBP is Yˆ = 43.2 + 0.17x. Identify the y intercept and the slope in this formula.
