erratic fluctuations

A savings and loan averages about $100,000 in deposits per week. However, because of the way pay periods fall, seasonality, and erratic fluctuations in the local economy, deposits are subject to a wide variability. In the past, the variance for weekly deposits has been about $199,996,164. In terms that make more sense to managers, the stan- dard deviation of weekly deposits has been $14,142. Shown here are data from a random sample of 13 weekly deposits for a recent period. Assume weekly deposits are normally distributed. Use these data and a = .10 to test to determine whether the variance for weekly deposits has changed.
