Which statement is not true about confidence level? A.) 99 percent confidence interval procedure has a higher probability of producing intervals that will include the population parameter than a 95 percent confidence interval procedure. B.) a confidence interval between 20 percent and 40 percent means that population proportion lies between 20 percent and 40 percent. C.) an approximate formula for a 95 percent confidence interval which is equal to the sample estimate plus minus margin of error. D.) a confidence interval is an interval of value computed from the sample data that is likely to include the true population value. The z value which is used to construct a 99 percent confidence interval? A.) 1.28 B.) 1.645 C.) 1.96 D.) 2.575
