Find the probability and interpret the results. If convenient, use technology to find the probability. The population mean annual salary for environmental compliance specialists is about $61,000. A random sample of 38 specialists is drawn from this population. What is the probability that the mean salary of the sample is less than $58,000? Assume o = $6,500. ... The probability that the mean salary of the sample is less than $58,000 is (Round to four decimal places as needed.) Interpret the results. Choose the correct answer below. A. About 22% of samples of 38 specialists will have a mean salary less than $58,000. This is not an unusual event. B. Only 22% of samples of 38 specialists will have a mean salary less than $58,000.

Determine whether this table represents a probability distribution.
Instructions Follow these steps: 1. Determine the random variable (what is being measured?) 2. Determine if the table below represents a probability distribution or not. 3. If it is a probability distribution, explain why (see the three criteria in the notes). If it is not a probability distribution, explain why not (which criteria are not met?) Here is the table: x: Number of answers correct on the quiz 0 1 2 3 4 You may use this "sentence frame" to make your post: The random variable is because P(X) .092 .124 .199 .583 .002 The table (is/is not) a probability distribution
