This problem relates to chapter 15 about parameters and sampling distributions
I'm confused do i just subtract the number from mean and divide by the standard deviation?
A manufacturing process produces bags of cookies.The distribution of weights of these bags should have a mean of 15.0 oz and a standard deviation of 0.4 oz.
1.) What is the probability that the weight of a bag of cookies chosen at random is greater than 15.7 oz?
2.) What is the probability that the mean weight of 9 bags is less than 14.9 oz?
3.) What is the probability that the mean weight of 9 bags is between 14.7 oz and 15.2?
