The weekly demand for Baked Lay's potato chips at a certain Subway sandwich shop is a normally distributed random variable with a mean of 450 and a standard deviation of 80. a. Find the z-score (standardized variable) for a week where 520 bags of chips are sold. b. Show a sketch of the normal distribution to support your answer. On your sketch, label the horizontal axis with the z-scores (-3, -2, -1, 0, +1, +2, +3) and include the appropriate x values that correspond to each of those z-scores. C. Clearly describe at least five characteristics of all normal distributions. In other words, under what conditions can we use a normal distribution?

The weekly demand for Baked Lay's potato chips at a certain Subway sandwich shop is a
normally distributed random variable with a mean of 450 and a standard deviation of
80.
a.
Find the z-score (standardized variable) for a week where 520 bags of chips are sold.
b. Show a sketch of the normal distribution to support your answer. On your sketch, label
the horizontal axis with the z-scores (-3, -2, -1, 0, +1, +2, +3) and include the appropriate x values that
correspond to each of those z-scores.
C.
Clearly describe at least five characteristics of all normal distributions. In other words,
under what conditions can we use a normal distribution?
