Sue buys a large packet of rice.The amount of rice that the manufacturer puts in the packet is a random variable with a mean of 1022 g and a standard deviation of 11 g.The amount of rice that Sue uses in a week has a mean of 240 g and a standard deviation of 26 g.Find the mean and standard deviation of the amount of rice remaining in the packet after a week.
A) μ = 1262 g,σ = 37 g
B) μ = 782 g,σ = 23.56 g
C) μ = 782 g,σ = 28.23 g
D) μ = 782 g,σ = 15 g
E) μ = 1262 g,σ = 28.23 g
Standard Deviation
A statistic that measures the dispersion or variation of a set of values relative to the mean.
Random Variable
A variable whose possible values are numerical outcomes of a random phenomenon, with each outcome having a probability associated with it.
Packet of Rice
A pre-measured, packaged amount of rice, typically sold in a sealed bag or box.
