Consider the following frequency table of 50 observations on the random variable X: Value Observed 2 10 Expected 8.8989 17.7979 14.8315 3 or more 15 8.4717 21 Based on the 50 observations, is a binomial distribution an appropriate model? Perform a goodness-of-fit test with a = 0.05, degrees of freedom (k –p – 1) = 3 Question 1: State the parameter of interest Question 2: Formulate the null and alternative hypothesis Question 3: Find the value of the critical Chi-Square, xã k-p-1 Question 4: Test the hypothesis if the distribution of the random variable X follows the binomial distribution a. Because X + X? , Question 1 reject the null hypothesis. Distribution is Question 2 binomial. Question 3 b.Họ: Distribution of random variable X is not binomial H;: Distribution of random variable X is binomial Question 4 c 12.84 d. Because X > x? reject the null hypothesis. Distribution is not *a,k - p -1 binomial e. Parameter of interest is the distribution of the random variable X f. Ho: Distribution is binomial
