Explain what appears to be the improved trade-off between inflation and unemployment in the U.S. What factors might improve the trade-off? What factors would make it worse?

Suppose x is a normally distributed random variable with µ = 10 and σ = 2. Find P (5 ≤ x ≤ 9)

"Biologists want to set up a station to test alligators in the lake for West Nile Virus. Suppose that the costs for such a station are $2,500 for setup costs and $3.00 to administer each test.a. As the number of animals tested increases, what happens to the average cost to test the animals? Would the average cost ever fall below $3.00?b. How many animals should be tested for the average cost to be $5.00 per animal?"

"An internal study by the Technology Services department at Lahey Electronics revealed company employees receive an average of two emails per hour. Assume the arrival of these emails is approximated by the Poisson distribution. a. What is the probability Linda Lahey, company president, received exactly 1 email between 4 P.M. and 5 P.M. yesterday? b. What is the probability she received 5 or more email during the same period? c. What is the probability she did not re...

" Write out exact expressions (in terms of Q, K, and L) for the OLS ‘normal equation’ (4 equations in 4 unknowns) for a data set with 50 observations.Returns to scale (RTS) in a 3-factor Cobb-Douglas production function are given by γ_1+γ_2+γ_3. If OLS is unbiased, will the sum of the OLS slopes in our model provide an unbiased estimator for returns to scale? Explain.Rewrite this model so that it will always exhibit constant RTS (i.e., γ_1+γ_2+γ_3=1). Simplify terms so that y...

If your employer asked you to review the decisions NOT TO HIRE any non-Hispanic applicants for jobs in your firm, what would you need to consider?

How many years will it take for carbon-14 to diminish to 1% of the original amount after the death of a plant or animal? Use the formula A=A0e(-0.000124t). Compute the answer to three significant digits.

"Calculate the test statistic and p-value for each sample. Use Appendix below to calculate the p-value. Suppose you always reject the null hypothesis, regardless of any sample evidence. What is the probability of Type I error? "

"1. Calculate separate confidence intervals for the numbers of days absent for Clinic A and Clinic B, respectively.2. The Health Authority is worried that if the mean days absent in either clinic reach 20 days, it will have difficulties safely operating the clinics. Conduct separate hypothesis tests for Clinics A and B (at 95% confidence) that demonstrate whether they can be confident that absence is less than 20 days."

"Conduct a two tailed hypothesis test given the information below. Assuming that the population standard deviations are unknown but equal for male and female GPA, use the following sample data to test whether the GPA are different at the 0.05 level of significance.Male GPA'sSample size 13Sample mean 3.6Sample standard dev 0.4Female GPA'sSample size 16Sample Mean 3.8Sample standard dev 0.7"

"Imagine a society that produces military goods and consumer goods affectionately known as ""guns"" and ""butter"". a. Draw a production possibilities frontier for this economy.  Show a point that is: inefficient; efficient; impossible. Explain why your frontier has a ""bowed out"" shape. b. Assume that this society has two political parties- Hawks (who support a strong military) and Doves (who prefer ...
