The mean chicken weight is 5lb, with a std dev of 1 lb. We want to take a simple random sample of 100 chickens.  

  1. What is the probability that the sample mean is between 4.9 and 5.1 lb?
  2. What is the probability that the combined weight of the chickens between 490 and 510 lb?
  3. Find the value a, such that the combined weight exceeds a with probability 95%.
  4. Find the value b, such that the combined weight is below b with probability 99%.

Cable Strength As a reminder, here again is the example from the previous page. A group of engineers developed a new design for a steel cable. They need to estimate the amount of weight the cable can hold. The weight limit will be reported on cable packaging. The engineers take a random sample of 45 cables and apply weights to each of them until they break. The mean breaking weight for the 45 cables is xbar =768.2 lb. The standard...

1A) An experiment was designed to estimate the mean difference in weight gain for pigs fed ration A as compared with those fed ration B. Eight pairs of pigs were used. The pigs within each pair were litter-mates. The rations were assigned at random to the two animals within each pair. The gains (in pounds) after 45 days are shown in the following table. Assuming weight gain is normal, find the 95% confidence interval estimate for the mean of the...

(7) A new drug is developed to treat headache, and we want to compare its performance with an existing drug. The performance measure here is the time from taking the drug to people start to feel better. A random sample of volunteers were collected, in one occasion of headache, these people use one of the drug, and then in another occasion of headache (there is a long time between occasions), these volunteers use the other drug. Assuming all variables are...
