Assume that a sample is used to estimate a population proportion p. Find the margin of error E that corresponds to the given statistics and confidence level. Round the margin of error to four decimal places. 98% confidence; the sample size is 800 of which 40% are successes 0.0339 0.0446 0.0403 0.0355 1 points Question 2 Find the value of that corresponds to a confidence level of 91%. 1.75 1.34 1.645 1.70 1 points Question 3 Find the appropriate critical value for the following: 99% confidence level ; n = 17; is unknown; population appears to be normally distributed. z/2 = 2.567 z/2 = 2.583 t/2 = 2.898 t/2 = 2.921 2 points Question 4 Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p. n = 195 x = 162; 95% confidence 0.788
