Given the following data for Q (units sold), a normally distributed random variable, calculate E[Q] or the mean of unit sales and S[Q] or the sample standard deviation of unit sales using Microsoft Excel. Think of this sample of data being collected from the last five years, or think of it as being collected in just one year from five different markets. Here is the data for Q:
18,000 units 25,000 units 25,000 units 25,000 units 32,000 units
E[Q] = ______________________ (round-off to the nearest unit)
S[Q] = ______________________ (round-off to the nearest unit)
