Question:
Last year, sanitation engineer crews in Buffalo, New York, collected 124 tons of trash per day. Th is year, larger, more efficient trucks were purchased. A sample of 100 truck-days shows that a mean of 130 tons of trash were collected, with a standard deviation of 30 tons. What is the probability that a sample with this mean could be drawn if the new trucks are no improvement (i.e., the population mean = 124)?
