To determine if a distribution is approximately normal we need to know the ___. Skewness Kurtosis Variance Skewness and Kurtosis Skewness and Variance Kurtosis and Variance Skewness, Kurtosis, and Variance
nerating function for Poisson 199. Cumulant ulant generating function of XPoisson(A) and then find its skewness coefficient and kurtosis coefficient nerating function for Poisson 199. Cumulant ulant generating function of XPoisson(A) and then find its skewness coefficient and kurtosis coefficient
what is the purpose of skewness and kurtosis ? How are they “read” from a graph? how do investors/ stock market people use skewness and kurtosis ?

Using Excel, calculate the mean, standard deviation, standard error, median, sample variance, kurtosis, skewness, range, minimum, maximum, sum, count, largest(1), smaller(1) of your distribution and interpret their meanings. Column Mean Standard error Median Mode Standard Deviation Sample variance Kurtosis Skewness Range Minimum Maximum Sum Count Largest(1) Smallest(1)
please help (b) In a continuous distribution, the frequency density function is given by Find yo, mean, variance, coefficients of skewness and kurtosis. Hence comment on 7 the nature of the distribution. The joint distribution of X and Y is given by (a) (x y #x, y)-Cxy e-(x" +y"),X20, y20. Find C. Test whether X and Y are independent. Also find the conditional density of X given Y- y. (b) In a continuous distribution, the frequency density function is given...
Skewness and kurtosis should not be tested when using the chi-square test of independence. True or False The major difference between the Mann-Whitney U-test and the Kruskal-Wallis H test is the number of independent variables. True or False
