Mathematics majors generally have one of the highest starting salaries. Suppose the average starting salary for mathematics majors is $48000 with a standard deviation of $6900. Find the probability that 35 mathematics majors have an average starting salary less than $48079 thousand.
Suppose you do average starting salary is $50,000 with a standard deviation of $5,000. an analysis of the starting salaries of 100 recent Lehman graduates. You find that the (5 points) Find the 90% critical values. a. (5 points) Find the 95% critical values. b.
2. You are planning a survey of starting salaries for recent computer science majors. In the latest survey by the National Association of Colleges and Employers, the average starting salary was reported to be $61,287. If you assume that the standard deviation is $3850, what sample size do you need to have a margin of error equal to $500 with 95% confidence? (report as an integer) 3. Suppose that in the setting of question 2 you have resources to contact...
#911. Teacher Salaries Based on the 2017-2018 Average Starting Teacher Salaries by State measured by NEA, the average starting salary for teachers in Rhode Island is $41,689, the sample size is 4,900 and the standard deviation is $458.58.

Specifically, provide the value for X: $41,689 +...
Starting salaries of 70 college graduates who have taken a statistics course have a mean of $44,644. Suppose the distribution of this population is approximately normal and has a standard deviation of $9,466. Using a 93% confidence level, find both of the following: (NOTE: Do not use commas or dollar signs in your answers.) (a) The margin of error: :
#462. Teacher Salaries Based on the 2017-2018 Average Starting Teacher Salaries by State measured by NEA, the average starting salary for teachers in Pennsylvania is $44,647, the sample size is 6,241 and the standard deviation is $759.00 If we want to get a 80% confidence interval with a small margin of error, say only 19. How many people do you need to sample? (Since a fraction of a person does not make sense, make sure to give the next largest...
