The weight of a randomly selected bag of corn chips coming off an assembly line is a random variable with mean=11oz. and standard deviation=0.

The weight of a randomly selected bag of corn chips coming off an assembly line is a random variable with meanμ=11oz. and standard deviationσ=0.2oz.

a. Suppose we pick five bags at random assume that weight of each of the bags are independent. The combined weight of these five bags is a random variable with a mean of…? 

b. The weight of a randomly selected bag of corn chips in pounds (1 pound = 16 oz.) is a random variable with standard deviation

a) 2 poundsb) 0.01 poundsc) 3.20 poundsd) 2.20 poundse) 0.05 poundsf) None of the above

what are the steps to solve this?
