A random sample of 100 people was taken. Eighty-five of the people in the sample favored Candidate A. We are interested in determining whether or not the proportion of the population in favor of Candidate A is significantly more than 80%. We consider the following sets of hypothesis testing: (A) Ho: p > 0.8; Ha: p ≤ 0.8 (B) Ho: p ≤ 0.8; Ha: p > 0.8 (C) Ho: p > 0.8; Ha: p < 0.8 (D) Ho: p = 0.8; Ha: p ≠ 0.8 Fill in Multiple Blanks: The correct set of hypotheses is . (Enter A, B, C, or D.) The actual value of the test statistic is _____________________. In your answer, show two (2) digits to the right of the decimal point, for example, 1.00, 1.20, 1.22. Apply the appropriate rounding rule if necessary. The p-value is _________________. In your answer, show four (4) digits to the right of the decimal point, for example, 1.0000, 1.2000, 1.2200, 1.2220, 1.2222. Apply the appropriate rounding rule if necessary. At the 10% significance level, we (reject, do not reject) Ho and conclude that the proportion of the population in favor of Candidate A (is, is not) significantly greater than 80%.
