Question
Estimate the number of workers in the sample who are union members by giving the mean of the relevant distribution (that is, the expectation of the relevant random variable). Do not round your response.
Solution
In order to estimate the number of workers in the sample who are union members by giving the mean of the relevant distribution, we need to have some data or information about the distribution. The mean (or expectation) of a distribution is calculated by multiplying each possible outcome by its probability and then summing these products. However, without specific data on the number of workers and the proportion who are union members, it's impossible to provide a specific estimate.
Here is the general formula for the expectation (E) of a random variable X:
E(X) = Σ [x * P(X=x)]
where:
- x is a possible outcome of X,
- P(X=x) is the probability of x occurring.
If you have the necessary data, you can substitute into this formula to find your answer.

A union of restaurant and foodservice workers would like to estimate the mean hourly wage, μ, of foodservice workers in the U.S. The union will choose a random sample of wages and then estimate μ using the mean of the sample. What is the minimum sample size needed in order for the union to be 99% confident that its estimate is within $0.35 of μ? Suppose that the standard deviation of wages of foodservice workers in the U.S. is about $2.10.Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements).(If necessary, consult a list of formulas.)
