Moreover, the average annual salary for all male respondents was $54,600, compared with $50,600 for women.
Q1. What is the population of interest?
Q2. What is the measurement scale of salary?
Q3. Suppose a delayed questionnaire was received from a nurse whose annual salary was $180,000. Inclusion of the additional data will likely result in a much higher average annual salaries. Is there a way to overcome this? If yes, how?
Q4. Based on the reported results, could you conclude male nurses had a higher salary than female nurses? If yes, how? If no, why not and what additional information would enable you to make the comparison?
