Using the areas in Figure (the Empirical Rule), find the areas; (a) To the right of...
Use the Empirical rule to determine the following areas as the probabilities A| B |C 21. How big is the area (probability) of zone "B"? 22. How big is the area (probability) of zone "D"
1. It is inappropriate to apply the Empirical Rule to a population that is right-skewed a. True b. False 2. A frequency distribution usually has equal class/bin widths. a. True b. False 3. Measurements from a sample are called a, statistics. b. inferences parameters d. variables 4. Automobile exhaust emission of CO2 (milligrams per mile) is data. a. nominal b. ordinal c. interval d. ratio
The Empirical Rule is also known as the 68-95-99.7 Rule. Use the Z-score table to find what each of these numbers really is. To assist you, include a sketch and a probability expression for each case. Please show your work, thanks.
Use the Empirical rule to determine the following areas as the probabilities 21 How big is the area (probability) of zone "B"7 22. How big is the area (probability) of zone "D"? The mean height of males 20 years or older is 68 inches with a standard deviation of 3.53 inches. The mean height of females 20 years or older is 62 inches with a standard deviation of 2.53 inches. While a male is 75 inches tall, a female is...
Verify the empirical rule by using Table A, software, or a calculator to show that for a normal distribution, the probability (rounded to two decimal places) within a. 1 standard deviation of the mean equals 0.68. b. 2 standard deviations of the mean equals 0.95. c. 3 standard deviations of the mean is very close to 1.00. I need the copy and paste your R command and output
1) In a problem, what lets you know to use the Empirical Rule 68% - 95%- 99.76? Remember, Empirical Rule is a shortcut for X-Z-Table problems and X -Z-Table problems. 2) What key word(s) in a problem tell you to use the Normal Distribution X~ N (4, o)? 3) What key word(s) in a problem tell you to use The Sampling Distribution of the Sample Mean X~ N
