![Farmer McGregor is now growing carrots in a field. He is particularly interested in the
weight of his plants at harvesting. Let X denote the weight (g) of a carrot in McGregor's field.
Assume X - N(200, 400).
(1) The farmer has randomly sampled 16 plants. What is the probability that the mean of a random
sample of that size differs from the population mean by less than 10 g?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1631b80e-e5c5-4efa-981a-870865ee15a7%2F10c61dd9-c38c-4851-9764-4f89f77414ff%2Fmqitn39_processed.png&w=3840&q=75)
