Amachine that is programmed to package 1.20 pounds of cereal is being tested for its accuracy in a sample of 36 cereal boxes, the sample mean filling weight is calculated as 1.22 pounds. the population standard deviation is known to be 0.06 pounds. find the 95% confidence interval for the mean.

Hence, the 95% confidence interval for the mean is (1.2004, 1.2396).

Step-by-step explanation:

Since we have given that

Mean = μ = 1.20 pounds

n= 36

We need to find the 95% confidence interval for the mean.

So, z = 1.96

So, confidence interval would be

Hence, the 95% confidence interval for the mean is (1.2004, 1.2396).

answer: haha (: i’ll go see what it is

step-by-step explanation:

i think it might be a but you might want a second opinion
