Question 5 (1 point) If it were decided that the null hypothesis for the test in Question 2 would be rejected if p s 0.4453, then what would be the significance level of the test? Report your answer as a decimal with 2 decimal places. (The answer is not simply the value of 0.03 from Question 3 or the value of 0.01 from Question 4. This is a different situation.) Your Answer: Answer Save Question 6 (1 point) We would like to construct a confidence interval to estimate the proportion of all Canadians who have blue eyes, what sample size is required in order to estimate the proportion to within 0.05 with 95% confidence? As you should always do with sample size determination problems, always round up your decimal answer to the next higher whole number. Your Answer: Answer

Explanation / Answer

5) We need to calculate p-value, and the given information is not sufficient to answer the question.

6)

Assuming the proportion(p) = 0.5

Given, margin of error = 0.05 and 95% confidence level.

ME = ZCritical * {p(1-p)/n}1/2

Hence,

N = ZCritical2 * p * (1-p) / ME2

Zcritical = 1.96

So,

N = 1.962 * 0.5 * 0.5 / 0.052 = 385
