1) A journal article reports that a sample of size 5 was used as a basis for calculating at 95% CI for the true average natural frequency (Hz) of delaminated beams of a certain type. The resulting interval was (229.764, 233.504). Assume the population is normal. You decide that a confidence level of 99% would be more appropriate than a 95% level used. What are the limits of the 99% interval?

Part 1 of 3: The age when smokers first start from previous studies is normally distributed with a mean of 13 years old with a population standard deviation of 1.9 years old. A survey of smokers of this generation was done to estimate if the mean age has changed. The sample of 32 smokers found that their mean starting age was 14.3 years old. Find the 3-decimal small value of the 95% confidence interval of the mean Part 2 of 3 Find the 3-decimal large value of the 95% confidence interval of the mean Part 3 of 3 Find the 3-decimal margin of error

We want to estimate the number of pounds of ground beef produced during a month. The firm processes 25,000 cows every year in this plant, and samples 500 cows for this investigation. This sample produced ?̅= 290 lbs ground of beef per cow with a sample standard deviation of s = 40 lbs. The plant is paid $.75/lb for the beef. a) Find a 90% confidence interval for ground beef. b) The plant manager bragged about the productivity of his workers and gave them a bonus because he says they slaughtered 2,500 cows and made $560,000 for the plant this month. Should the board of directors investigate? Why or why not?
