A study of life expectancy showed that a random sample of 6 states had a standard deviation of 0.9 deaths per year. Find the 98% confidence intervals of the variance and standard deviation. Assume the variable is normally distributed. Use the chi-square distribution table to find any chi-square values to three decimal places. Round your final answers to one decimal place 20 21 Question 18 of 22 (1 point) Attempt 1 of Unlimited 74 Sacton Eame 8 Obesity Obesity is defined as a body mass index (BMI) of 30 kg/m or more. A 95% confidence interval for the percentage of U.S. men aged 18 to 29 who were obese was found to be 18.8% to 21.4%. What was the sample size? Round the intermediate calculations to four decimal places and round up your final answer to the next whole number. Your answer is incorrect.
