10.8. With reference to the data in Exercise 1.1, employing the chi-squared goodness-of-fit test, can it be concluded that the time lapses are not exponentially distributed with θ = 3.2 minutes? Use α = 0.01. Exercise 1.1: The following data are the lapses, in minutes, required for 50 customers of a commercial bank, to carry out a banking transaction:
