If the population standard deviation is 3 points, what minimum sample size is needed to be 90% confident that the sample mean is within 2 points of the true population mean? z0.101.282z0.051.645z0.0251.960z0.0 12.326z0.0052.576 Use the table above for the z-score, and be sure to round up to the next integer. Provide your answer below:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

=

=

=

⇒ option b is correct.
