A recent health report revealed that a woman with insurance spends an average of 2.3 days in the hospital following a routine childbirth, while a woman without insurance spends an average of 1.9 days at the hospital. Two samples of 16 women each were used in both samples. The standard deviation of the first sample is equal to 0.6 day, and the standard deviation of the second sample is 0.3 day. At ?=0.01, test the claim that the means are equal. Find the 99% confidence interval for the differences of the means and compare the result of the hypothesis test to the one for the confidence interval.

A recent agricultural study found that weight of a chicken follows normal distribution with a mean of 2 lbs and standard deviation of 0.3 lbs. Using this information, answer the following questions.

Eric is a farmer who claims that he owns a chicken such that only 1% of all the chickens will be expected to have weights greater than his chicken. What is the weight of Eric’s chicken?

Tom is a farmer who owns 50 chickens. What is the probability that the total weight of all the chickens on Tom’s farm will be greater than 105 lbs?

2. A pendulum exhibits simple harmonic motion when it is released at an angle θ = 9°. The length of the pendulum is l=0.86 m, and the pendulum bob has a mass m=0.3 kg.

a. What is the pendulum’s frequency?

b. Use energy conservation to find the pendulum bob’s speed when it passes through the lowest point of the swing? Assume that the difference in height between the lowest part of the swing and the highest part of the swing is delta H= l(1-cos(θ))

c. What is the total energy of the system?

Assume that there was a starburst that produced 1011 solar masses of stars with a minimum mass of 0.3 solar masses and a maximum mass of 100 solar masses. The number of stars as a function of mass is N(M) = KM-2.35, where K is a normalization constant. The current turnoff mass of the population is 1 solar mass

  1. Compute the number of stars and the total mass of stars that are still on the main sequence.
  2. Assume that all stars with masses between 1 and 8 solar masses became white dwarfs. Compute the total number of white dwarfs in this population

Assume in a Bertrand model, there are 3 identical firms in the market with the same constant marginal cost of 30. The demand function is P = 150 ? Q. Firms share the monopoly profit equally if they participate in the cartel. With probability 0.3 the cartel is detected by the end of period t, in which case each cartel member has to pay the fine $1000. Cartel investigation takes one period. If detected by the end of period t, the cartel is disbanded at the end of the period and the firms return to the noncooperative game permanently. Derive the condition required for the cartel to succeed
