A beverage company produces bottled water. The volume of the bottled water is 16.702 and quality control requires the standard deviation of volume be at most 0.202. A new production line is recently installed and you are asked to see if the producing process meet the quality control requirement. In order to find the answer, the quality control department has randomly sampled 60 bottles of water produced with the new production line and finds a sample variance of 0.03. X2 0.025.59=82-117. X2 0.05.59=77-93. X2 0.975,59=39-66. X2 0.95,59=42-34 Find a 95% interval for the volume variance. Select one: C a. [003223,004141] O b. [0.02155, 0.04463] C? c. [003,004] C? d.

The senate is granted permission to conduct a survey, in an attempt to provide statistical evidence disproving the university officials' claim. To perform the test a random sample of 568 students were surveyed of which 91 responded \"yes" to "Do you regularly smoke?". t00253451993. t0.05,74='|-666, 20.025=1'960r Zo.o5=1-545 What is the required sample size for constructing a 90% confidence interval with a width of 0.006 given the a priori idea extracted from the above sample ? Hint 1: use as many decimal places as possible in your calculations. Hint 2: Width is not the same as total length of the interval. Select one: C': a. 11453 A b. 10316 a\"? c. 10114 C?
