Question
B) There are __ degrees of freedom.
C) The critical value is ___
D) Should the null hypthesis be rejected?
*No, because X^2/0 is less than or equal to x^2/0.05
*No because X^2/0 is greater than X^2/0.05
*Yes Because X^2/0 is less than or equal to X^2/0.05
*Yes Because X^2/0 is greater than X^2/0.05
x 3 Determine (a) the X2 test statistic (b) the degrees of freedom (c) the critical value using = 0.05 and (d) test the hypothesis at the = 0.05 level of significance. 0 4 37 121 441 390 1 2 Observed Expected 1.6 25.4 152.5 406.7 406.7 Ho: The random variable X is binomial with n= 4, p= 0.8 H1: The random variable X is not binomial with n= 4, p : 0.8 (a) The test statistic is (Round to two decimal places as needed.)Explanation / Answer
Answer:
Test statistic = 18.98
B) There are 4 degrees of freedom.
C) The critical value is 9.488
D) Should the null hypothesis be rejected?
*No, because X^2/0 is less than or equal to x^2/0.05
*No because X^2/0 is greater than X^2/0.05
*Yes Because X^2/0 is less than or equal to X^2/0.05
Answer: *Yes Because X^2/0 is greater than X^2/0.05
