Fifty-three percent of employees make judgements about their co-workers based on the cleanliness of their desk. You randomly select 8 employees and ask them if they judge co-workers based on this criterion. The random variable is the number of employees who judge their co-workers by cleanliness. Which outcomes of this binomial distribution would be considered unusual? 1, 2, 7, 8 1, 2, 8 0, 1, 7, 8 0, 1, 2, 8 Sixty-eight percent of products come off the line within...
Employees at an engineering firm were sampled and the following probability data was collected on how many days per week they work. Days 1 2 3 4 5 6 7 Probability 0.02 0.05 0.10 0.12 0.60 0.10 0.01 1. If an employee is selected at random from this company, what is the probability that they work less than five days per week? 2. What is the expected value of the number of days per week worked by an employee at...
Twenty-five percent of the employees of a large company are minorities. A random sample of 9 employees is selected. Round answers to the nearest thousandths (3 decimal places). What is the probability that the sample contains exactly 4 minorities? a. (1 point) What is the probability that the sample contains fewer than 2 minorities? b. (1 point) What is the probability that the sample contains exactly 3 non-minorities? C. (1 point) What is the expected number of minorities in the...
