= A simple random sample of size n = 20 is drawn from a population that is normally distributed and the sample variance was found to be 49.3. A chi-square test was performed to determine if the population variance is less than 95 at the a = 0.1 level of significance and the following output was obtained: x3 = 9.86, Px < 9.86) = 0.0437 Which of the following is the appropriate conclusions? (circle one answer) (a) There is no sufficient evidence, p < 0.1 to conclude that the population variance is less than 95. (b) Given that p < 0.1 we conclude that the population variance is not less than 95. (C) There is sufficient evidence, p < 0.1, to conclude that the population variance is less than 95. (d) The x2 test is not appropriate test to use to make conclusions about the variance.
