Assuming that workers' salaries in your company are uniformly distributed between $20,000 and $50,000 per year, calculate the average salary in your company.
here for uniform distribution: parameter a =20000 and b=50000 ; therefore
average salary in your company =(a+b)/2 =(20000+50000)/2 =35000

Annual salaries for employees in a large company are approximately normally distributed with a mean of $50,000 and a standard deviation of $20,000. What percentage of company workers make under $40,000?
An economist with the Liquor, Hospitality and Miscellaneous Workers' Union collected data on the weekly salaries of workers in the hospitality industry in Cairns and Townsville. The union believed that the weekly salaries in Cairns were higher and they were mounting a case for the equalisation of salaries between the two cities. The researcher took samples of size 28 and 34 in Cairns and Townsville respectively, and found that the average and standard deviation of the weekly salaries were $588.50...
The annual salaries of employees in a large company are normally distributed with a mean of $50,000 and a standard deviation of $20,000. What percentage of people earn between $45,000 and $65,000? Round to the second decimal place.
Question 2. Based on a survey, workers in Ontario earn an average of $60,000 per year with a known standard deviation of $6000. In an attempt to verify this salary level, a random sample of 36 workers in Ontario was selected. Let X represent the mean salary of these 36 workers. a) Describe the sampling distribution of X. b) Calculate the probability that X is between 58,500 and 63,000. c) What is the 90th percentile for X.
