Question

Can you check my work?
A simple random sample of forty 20-oz bottles of Coke from a normal distribution is obtained and each bottle is measured for number of ounces of Coke in the bottle.
The sample had 11 bottles with less than 19.8 oz. Consumers want to sue if more than 3% of the bottles are under 19.8 oz. Do they have enough evidence to sue?

Answer 1

ok so \(H_0: p \le .03\) and \(H_A: p>.03\)

Answer 2

now we need the z-test

Answer 3

so we get z= 9.0834
Which means are probability of this occuring is almost zero. So, I reject my H_0 and decide that the consumers have enough evidence to sue
