Question 2 1 / 2 pts We wish to calculate a confidence interval for an unknown population proportion 7 given a sample of 35 successes out of 50 trials (sample proportion p = 0.7). The standard error implied by this sample is 0.0648. A 68% confidence interval calculated for the population proportion given these data is [0.6352, 0.7648]. A 95% confidence interval is [0.5730, 0.8270]. The 68% confidence interval is less accurate and less precise, than the 95% confidence interval. Answer 1: less accurate Answer 2: or more less precise
