(a) Find the standard deviation of the expenditure at both cities.

(b)  Find out which of the city shows greater variability.

5. (a) The following results have been ascertained from the time series data with the help of least square method. The duration of the time is from the year 2001 to 2007.

N = 7, =532, Ix = 0, /,xy = 136 /x2 =28
