Find the right critical value for a 94% confidence interval using the chi-square distribution with sample size of 16. Round to two decimal places. 1 pts Question 2 Find the left critical value for a 93% confidence interval using the chi-square distribution with sample size of 24. Round to two decimal places. Question 3 1 pts The compressive strengths of nine concrete blocks, in pounds per square inch, are measured, with the following results. 1982.7 1994.1 2073.2 2074.6 2070.1 2070.9 2073.8 2033.6 1937.1 Assume these values are a simple random sample from a normal population. Construct a 95% confidence interval for the population standard deviation. n= $2 Round to four decimal places. left critical value = Round to four decimal places. right critical value = Round to four decimal places. We are 95% confident that the population standard deviation of the compressive strengths of concrete blocks are between and Ibs/in2. Round to two decimal places
