Mean entry-level salaries for college graduates with mechanical engineering degrees and electrical engineering degrees are believed to be approximately the same. A recruiting office thinks that the mean mechanical engineering salary is actually lower than the mean electrical engineering salary. The recruiting office randomly surveys 48 entry level mechanical engineers and 52 entry level electrical engineers. Their mean salaries were $46,000 and $46,800, respectively. Their standard deviations were $3450 and $4210, respectively. Conduct a hypothesis test at the 5% level to determine if you agree that the mean entry- level mechanical engineering salary is lower than the mean entry-level electrical engineering salary.
1.State the distribution
2. What is the test statistic?
3. What is the P-Value?

Salaries of entry-level computer engineers have Normal distribution with unknown mean and variance. Than sample standard deviation of three sample is 20 and sample mean is 50,000. Does this sample provide a significant evidence, at a 10% level of significance, that the average salary of all entry-level computer engineers is less than $80,000? Explain (Hypothesis testing)

A large university is well known for both its business school and its mechanical engineering program. The dean of the career services office wants to know if there is a difference in starting job salary between recently graduated business majors and mechanical engineering majors. The starting annual salaries for a random sample of 30 business majors and 30 mechanical engineering majors from the most recent graduating class are taken. Assume that the population standard deviation of the business majors' starting...

{Exercise 8.27 (Algorithmic)}. Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $40,000 and $50,000. Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. What is the planning value for the population standard deviation (to the nearest whole number)? 3750 How large a sample should be taken if the desired margin of error is as shown below to the nearest whole number)? a. $500? 216...

Answer ALL questions please!
1. Records of 40 used passenger cars and 40 used pickup trucks (none used commercially) were randomly selected to investigate whether there was any difference in the mean time in years that they were kept by the original owner before being sold. For cars the mean was 5.3 years with standard deviation 2.2 years. For pickup trucks the mean was 7.1 years with standard deviation 3.0 years. a. Construct the 95% confidence interval for the difference...

RIS BOHNET THINKS firms are wasting their money on diversity training. The problem is, most programs just don’t work. Rather than run more workshops or try to eradicate the biases that cause discrimination, she says, companies need to redesign their processes to prevent biased choices in the first place. Bohnet...
