"A sample of 12 packages of chips is chosen from a shipment in which the weights of the packages are known to be normally distributed. The sample has an average weight of 106 grams, with a standard deviation of 5.2 grams. Is there evidence that the packages weigh significantly more than the 100 grams on the label?"

Choose the best checking of conditions.

Question 7 options:

	It is normally distributed, so conditions for a TTest are met.
	It is not normally distributed, so conditions for a TTest are not met.
	np(1-p) > 10, so conditions for a 1-PropZTest are met.
