Knowledge Objective: Uniform Continuous Distribution Tensile tests of a 3D printed material show that the average yield strength of that material is about 800 MPa with a standard deviation of 40 MPa. Due to the variations of the process parameters, the yield strength can vary, and historical data show that yield strength of the material follows a uniform continuous distribution. Answer questions 1a to 1e using this information. 1a. What is the random variable (X)? a. Value of the most...

Does anyone have experience with during a lab on conducting a 2-sample t-test at a 1% level of significance to find out if the U.S. stock returns significantly outperform the U.S. bond returns using the monthly data covering the sample period of 1980-2017? Draw conclusions by both the P Value and Critical Value Method. Arnavbha - I have an excel spreadsheet with data, but how do I get it to you?

1. Macroeconomics does not try to answer the question of: a. why do some countries experience rapid growth? b. what is the rate of return on education? c. why do some countries have high rates of inflation? d. what causes recessions and depressions. 2. How does the distinction between flexible and sticky prices impact the study of macroeconomics? a. The study of flexible prices is confined to microeconomics, while macroeconomics focuses on sticky prices. b. Macroeconomists use flexible prices to...
