Please ONLY use excel or i will not be able to learn the concept For a random sample of 100 cans of peaches: 󠅜x ̅ = 15.9 ounces and s= 0.09 ounces a- Find the margin of error at the 95% confidence level b- Find the margin of error at the 95% confidence level if the sample size was only 20 c- What sample size at the 95% level is necessary to get the margin of error down to 0.005 ounces?
Added by Jasmine J.
Step 1
To find the margin of error, we use the formula: Margin of Error = Critical Value * Standard Deviation / Square Root of Sample Size First, we need to find the critical value. Since we are working with a 95% confidence level, we need to find the z-score that Show more…
