Solution to Example 4: The sample space of the experiment "2 dice" is shown below. a) E1 and E2 are not mutually exclusive because outcome (5,5) is a double and also gives a sum of 10. The two events may occur at the same time. b) E2 and E3 are not mutually exclusive because outcome (1,1) is a double and gives a sum of 2 and is less than 4.The Length of a certain species of fish has a normal distribution with mean 50 mm and standard deviation 4.5 mm.

This is the probability that a score will be lower than our raw score, but the question asked the proportion who would be taller. Final Answer (in words): The probability that a woman in the U.S. would be 64 inches or taller is 0.4562, or 45.62% 45.62 %. Your turn!Answer: The price elasticity of demand is 1, which is the derivative of ln(Q t) with respect to ln(P t). Suppose you have annual data on Q_t, P_t, and Y_t in Cambridge for 30 years, and that you have some other annual data available too. You are interested in estimating the coefficients of equation (1).

Use a Z test when you need to compare group means. Use the 1-sample analysis to determine whether a population mean is different from a hypothesized value. Or use the 2-sample version to determine whether two population means differ. A Z test is a form of inferential statistics. It uses samples to draw conclusions about populations.Empirical Rule Practice Problems. The Empirical Rule, sometimes called the 68-95-99.7 rule, states that for a given dataset with a normal distribution: 68% of data values fall within one standard deviation of the mean. 95% of data values fall within two standard deviations of the mean. 99.7% of data values fall within three standard deviations ...The solution to a multiplication problem is called the “product.” For example, the product of 2 and 3 is 6. When the word “product” appears in a mathematical word problem, it is a sign that multiplication is necessary.Step 1: Determine the mean of the observations, i.e. Arithmetic mean. Step 2: Calculate the squared deviations from the mean, i.e. (Data value – Mean) 2.
