Determine (a) the yo test statistic, (b) the degrees of freedom, (c) the P-value, and (d) test the hypothesis at the a = 0.05 level of significance. X 0 1 2 3 4 Observed 5 39 122 437 388 Expected 1.6 25.4 152.2 405.9 405.9 Ho: The random variable X is binomial with n = 4, p = 0.8 H: The random variable X is not binomial with n = 4, p = 0.8 Click the icon to view the chi-square distribution table. (a) xo =] (Round to two decimal places as needed.) (b) There are degrees of freedom. (c) The P-value is (d) What is the conclusion of the test at the a = 0.05 level of significance? the null hypothesis, because the P-value is than There evidence that the random variable X is not binomial with n = 4, p = 0.8
