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. 0 1 2 3 4 0 Observed 3 41 123 439 389 Expected 16 25.5 152 8 407 6 407 .6 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) x8 =0 (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
