The statistics of n=22 and s=14.3 result in this 95% confidence interval estimate of σ: 11.0<σ<20.4. That confidence interval can also be expressed as (11.0, 20.4). Given that 15.7+_4.7 results in values of 11.0 and 20.4, can the confidence interval be expressed as 15.7+_4.7 as well? Choose the correct answer below. A. Yes. In general, a confidence interval for σ has s at the center. B. Yes. Since the chi-square distribution is symmetric, a confidence interval for can be expressed as 15.7+_4.7. C. No. The format implies that s=15.7, but s is given as 14.3. In general, a confidence interval for σ does not have s at the center. D. Not enough information

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
