The weights of cans of Ocean brand tuna are supposed to have a net weight of 6 ounces. The manufacturer tells you that the net weight is actually a Normal random variable with a mean of 5.95 ounces and a standard deviation of 0.2 ounces. Suppose that you draw a random sample of 42 cans. Part i) Suppose the number of cans drawn is doubled. How will the standard deviation of sample mean weight change? O A. It will decrease by a factor of 2. O B. It will decrease by a factor of v2. O C.It will increase by a factor of y2. O D. It will increase by a factor of 2. O E. It will remain unchanged. Part ii) Suppose the number of cans drawn is doubled. How will the mean of the sample mean weight change? O A. It will increase by a factor of V2. O B. It will decrease by a factor of v2. O C.It will increase by a factor of 2. O D. It will decrease by a factor of 2. O E. It will remain unchanged.
