Been having an issue with these specific homework problems. Can you give me some insight on where to start.(adsbygoogle = window.adsbygoogle || []).push({});

#4.78 F

The actual amount of juice that a machine fills the juice boxes with is 4-ounces, which may be a random variable with normal distribution of [tex]\sigma[/tex] = 0.04 ounce

a) If only 2% of the boxes contained less than 4 ounces what is the mean/average fill on the juice boxes

b) If the variability of the machine that fills the boxes are reduced to 0.025 oz, confirm that the lower required average/mean amount of juice to 4.05 oz and keeping the 98% of jars above 4 oz

I have no idea where to start... Please help thanks
