Suppose that a GARCH(1,1) model is estimated from daily data as (^2)n = 0.000005 + 0.17u^2 n1 + 0.95^2 n1 and that on day n

Suppose that a GARCH(1,1) model is estimated from daily data as (σ^2)n = 0.000005 + 0.17u^2 n−1 + 0.95σ^2 n−1 and that on day n − 1 the market variable decreased by 2%  Suppose that the estimate of the volatility on day n − 1 is 2.15% per day

 calculate a new estimate of the volatility.
