3. Take the mean and standard deviation of data set A calculated in problem 1 and assume that they are population parameters (μ and σ) known for the variable fish length in a population of rainbow trouts in the Coldwater River. Imagine that data set B is a sample obtained from a different population in Red River (Chapter 6 problem!).

a) Conduct a hypothesis test to see if the mean fish length in the Red River population is different from the population in Coldwater River.

b) Conduct a hypothesis test to see if the variance in fish length is different in the Red River population compared to the variance in the Coldwater population.

please explain to me how to do this step by step. thank you!

Among 800 subjects who completed four years of college, 145 of them smoke. At the 0.04 significance level, use the p-value method test to claim that among college graduates, less than one in five smoke.

(a) State the null and alternate hypothesis

(b) Find the value of the test statistic and the p-value

(c) If a=0.04, are the test results significant or insignificant? Explain in words your conclusion

1. Suppose that a researcher is conducting a study on fast food habits and assumes that 55% of adults prefer hamburger to pizza. He randomly selects 10 adults and ask whether they prefer hamburger to pizza or not. Based on this information, answer the following questions.

a) (20 pts) Define the random variable (in words) and check whether it is a binomial random variable or not and write your conclusion. Explain your answer.

b) (10 pts) What is the probability that at least 8 adults prefer hamburger?

c) (10 pts) What is the probability that as most 3 adults prefer hamburger?

d) (15 pts) What is the expected number of people who prefer hamburger.

e) (15 pts) Calculate the standard deviation of this random variable and interpret it.

Annual expenditures for prescription drugs was $838 per person in the Northeast of the country. A sample of 60 individuals in the Midwest showed a per person annual expenditure for prescription drugs of $745. Suppose the population standard deviation is $300. Follow the steps below to develop a hypothesis test to determine whether the sample data support the conclusion that the population annual expenditure for prescription drugs per person is lower in the Midwest than in the Northeast.

1. Formulate the null and alternative hypotheses.  State whether this is a one-tailed test (and if so, upper or lower tail) or a two-tailed test.
2. Suppose the significance level is . Explain what this means.
3. Calculate the test statistic. (Hint: Is  known or unknown?)
4. Calculate the p-value and make a decision to either reject  or to fail to reject .
5. Calculate the critical value(s). Use the test statistic then to make a decision to either reject  or to fail to reject .
6. State what your decision means in the context of the problem (prescription expenditure in the Midwest vs. the Northeast).
