number of blocked intrusions

Consider the data about the number of blocked intrusions in Exercise 8.1, p. 233.

(a) Construct a 95% confidence interval for the difference between the average number of intrusion attempts per day before and after the change of firewall settings (assume equal variances).

(b) Can we claim a significant reduction in the rate of intrusion attempts? The number of intrusion attempts each day has approximately Normal distribution. Compute Pvalues and state your conclusions under the assumption of equal variances and without it. Does this assumption make a difference?

Exercise 8.1

1. List 20 situations involving uncertainty that happened with you yesterday.

2. Name 10 random variables that you observed or dealt with yesterday.

3. Name 5 stochastic processes that played a role in your actions yesterday.

4. In a famous joke, a rather lazy student tosses a coin and decides what to do next. If it turns up heads, play a computer game. If tails, watch a video. If it stands on its edge, do the homework. If it hangs in the air, prepare for an exam.

(a) Which events should be assigned probability 0, probability 1, and some probability strictly between 0 and 1?

(b) What probability between 0 and 1 would you assign to the event “watch a video,” and how does it help you to define “a fair coin”?
