Translate the statement into a confidence interval. Approximate the level of confidence. In a survey of 1000 adults in a country, 68% said being able to speak the language is at the core of national identity. The survey's margin of error is + 3.2%. The confidence interval for the proportion is (Round to three decimal places as needed.) The interval is a % confidence interval. (Round to one decimal place as needed.)Find the critical values x2, and x2p for the given confidence level c and sample size n. c = 0.99, n = 22Find the critical values x and x for the given confidence level c and sample size n. c = 0.90, n = 16Use technology to construct the confidence intervals for the population variance o and the population standard deviation o. Assume the sample is taken from a normally distributed population. c= 0.99, s2 = 7.84, n= 30
