In a simple random sample if 25 law school graduates, you find the sample mean starting salary ̄X= $31,500 and the sample standard deviation s = $3000.Suppose further that the starting salary of law school graduates has a normal distribution. Carryout the following test of hypothesis at the level of significant α=.05.Determine the decision rule and your conclusion.Also, compute the observed level of significance for this test. H0:μ= 30,000 Ha:μ >30,000

Note: Please tell me which table you used when solve the problem.

1- It is believed that the mean μ starting salary for the new KU graduates has increased from last year,s mean of $51 K annually. It is known that the standard deviation of the starting salary is σ = 5 K. To test what you believe, you collect a sample of 15 new graduates and find that the sample mean salary is x= 54 K. In this question and the next two, we will do a significance test to determine...

Suppose you want to test for whether there is a difference in starting salaries for those with a finance degree compared to those with an accounting degree. You sample 35 graduates with a finance degree and find the average starting salary to be 58,000 with a sample standard deviation of 5,000. You also take a sample of 40 graduates with an accounting degree and find the average starting salary 56,000 to be and a sample variance of 3000. Suppose you...

For a random sample of 17 recent business school graduates beginning their first job, the mean starting salary was found to be $43,500, and the sample standard deviation was $8,500. Assuming the population is normally distributed, calculate the lower confidence limit (LCL) of the population mean with α = 0.10.

A recent national survey found that high school students watched an average (mean) of 7.6 DVDs per month with a population standard deviation of 0.5 hours. The distribution of times follows the normal distribution. A random sample of 61 college students revealed that the mean number of DVDs watched last month was 7.0. At the 0.01 significance level, can we conclude that college students watch fewer DVDs a month than high school students? Use α = 0.01. a. State the...
