Is there sufficient evidence at the a = 0.1 level of significance to conclude the proportion has changed since 2000? Write the conclusion in the contest of the problem and possible error. Choose the correct answer: A. At a = 0.1 level of significance, there is sufficient evidence to prove that the proportion has changed since 2000 with Type I error. B. At a = 0.1 level of significance, there is sufficient evidence to prove that the proportion has changed since 2000 with Type II error. C. At a = 0.1 level of significance, there is insufficient evidence to prove that the proportion has changed since 2000 with Type | error. D. At a = 0.1 level of significance, there is insufficient evidence to prove that the proportion has changed since 2000 with Type II error. E. None of these OA OB OC OD OE DELL
