Question

**Learning Log 19**

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 $ \bar{x} = 290 $ lbs ground of beef per cow with a sample standard deviation of $ s = 40 $ lbs. The plant is paid \$0.75/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?

Internet speeds are a heavily advertised selling point of Internet Service Providers. You notice that although you are paying for a certain speed, the true speed seems to vary depending on where you are in your house. In order to estimate the true average speed you are getting in your house, you go to 13 random spots around your house and record the speed (in MBs per second) shown from a test at 'www.speedtest.net'. You see that the average is 5.61 MB/s with a standard deviation of 1.274 MB/s. You decide to create a 99% confidence interval for the average internet speed in your house. What is the margin of error for this estimate?
