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 $61,500. A random sample of 33 specialists is drawn from this population. What is the probability that the mean salary of the sample is less than $59,000? Assume o = $6,500. The probability that the mean salary of the sample is less than $59,000 is- (Round four decimal places as needed.)

Consider the following. 22, 11, 33, 24, 21 Compute the population standard deviation of the numbers. (Round your answer to one decimal place.)  (a) Add a nonzero constant c to each of your original numbers and compute the standard deviation of this new population. (Round your answer to one decimal place.) (b) Use the results from part (a) and inductive reasoning to state what happens to the standard deviation of a population when a nonzero constant c is added to each data item. The standard deviation increases by c.The standard deviation remains the same.    The standard deviation becomes 0.The standard deviation decreases by c.The standard deviation becomes c.

To avoid unpleasant surprises when the statement comes, you try to record all your credit card transactions in  a ledger. Unfortunately, you tend to neglect recording about 5% of your purchases. Suppose that last month, you had 25 purchases on your credit card account. When the statement arrives, you count the number of purchases you forgot to record. The random variable X represents the number of unrecorded purchases in a month with 25 transactions. Find and interpret the mean

The mean height of women in a country (ages 20 – 29) is 63.9 inches. A random sample of 70 women in this age group is selected. What is the probability that the mean height for the sample is greater than 65 inches? Assume o = 2.91. The probability that the mean height for the sample is greater than 65 inches is (Round to four decimal places as needed.) Clear all Check answer Get more help -
