13. In a symmetric distribution : A. The median equals the mean B. The mean is less than the median C. The mean is greater than the median D. The median is less than the mode
Can I have a detailed, step-by-step explanation on Question 2? Thank you!
If the mode is greater than the median and the median is greater than the mean. which of the following statements is true? A) It is a platykurtic curve. B It is positively skewed. c) Most of the data is concentrated on the right side of the distribution. D It has a skewness value of greater than zero.
1. A Chi square distribution has 11 degrees of freedom. Find the x values corresponding to the following right- hand tail areas. a. 0.005. b. 0.975. c. 0.990 d. 0.025
25) Refer to the figure below. A ssume that all the distributions are symmetric (i.e. the sample mean and median are approximately equal) and that all the samples sizes are the same. Imagine carrying out two ANOVAS. The first ANOVA compares the means based on samples A, B, and C (left of the vertical line), and the second ANOVA compares the means based on samples X, Y, and Z (right of the vertical line). One of the calculated values of the F-statistic is 0.92 and the other is 33.54. Which value is which, and why? Data in HER2 on inv breast aloo sals imme e to 60 50 Che 30 20 10 A Group A) 33.54 goes with A, B, and C; 0.92 goes with X, Y, and Z. The F-statistic for A, B, and C is larger because the variation within groups is smaller relative to the variation between groups. B) 33.54 goes with A, B, and C;0.92 goes with X, Y, and Z. The F-statistic for A, B, and C is larger because the variation between groups is smaller relative to the variation within groups. C) 0.92 goes with A, B,…

. Which of the following statement is not correct and why? A. For normal distributions, the mean is the most efficient. B. Mean is good for skewed distributions because it takes into consideration of all the possible scores. C. Median is less sensitive to extreme scores than the mean. D. Mode becomes rather unimportant as a statistic when the distribution is multimodal. If the largest observation in a set scores is 99 and the smallest is 71, what is the range, show work? A. 1 B. 28 C. 71 D. 99 Which of the following statement is correct and why? A. The median is the mean trimmed 0% and the arithmetic mean is the mean trimmed 100%. B. A trimmed mean is calculated by discarding the lower and higher 25% of the scores then dividing the sum of the remaining scores by 2.…

Suppose that the speed at which cars go on the freeway is normally distributed with mean 80 mph and standard deviation 5 miles per hour. Let X be the speed for a randomly selected car. Round all answers to 4 decimal places where possible. a. What is the distribution of X? X- N b. If one car is randomly chosen, find the probability that it is traveling more than 76 mph. c. If one of the cars is randomly chosen, find the probability that it is traveling between 82 and 88 mph. d. 86% of all cars travel at least how fast on the freeway? mph. Submit Question
