Consider the observed frequency distribution for the accompanying set of random variables. Perform a chi-square test using o 0.05 to determine if the observed frequencies follow the Poisson probability distribution when 1.5. Total Random variable, x 4 and more Frequency, fo 34 30 17 100

Explanation / Answer

a)

a1. The chi-square test statistic is 2=6.2665

b2. Determine the p-value=0.1804

B)

b1. The chi-square test statistic is 2 =2.3505

b2. Find The chi-square critical value, rounded to three decimal places = 9.4877

b3.Determine the p-value and interpret its meaning.=0.6716; whcih is extreme probabilty of null hypothesis to be accepted
