Exercise 14.8. X is the outcome of a throw of a die. Let A be the event that X > 3 and B be the event that X is even. Let IA and I be the indicators associated with A and B (see the previous exercise). Find Cov(IA, IB) and P(IA, IB).
Frozen computer: A computer system administrator noticed that computers running a particular operating system seem to freeze up more often as the installation of the operating system ages. She measures the time (in minutes) before freeze-up for 6 computers one month after installation and for 6 computers seven months after installation. The results are shown. Can you conclude that the time to freeze-up is more variable in the seventh month than the first month after installation? Let σ1 denote the variability in time to freeze-up in the first month after installation. Use the α=0.10 level and the critical value method with the table. One month: 207.4 233.1 215.9 235.1 225.6 244.4 Seven months: 84.3 53.2 127.3 201.3 174.2 246.2 State the null and alternate hypothesis

The circuit shown below operates if and only if there is some path of functional devices from left to right. The probability that each device functions is shown for each device and the devices operate independently of each other. What is the probability that the circuit operates? 0.9 0.9 0.8 0.95 0.95 0.9 (A) None of these (B) 0.5263 (C) 0.1642 (D) 0.9850 (E) 0.9702
I need help with this:A manufacturer knows that on average 20% of toasters produced require repairs within 1 year after they are sold. When 18 toasters are randomly selected, find the smallest number x and largest number y such that (a) the probability that at least x of them will require repairs is less than 0.58; (b) the probability that at least y of them will not require repairs is greater than 0.84.
Semiconductor lasers used in optical storage products require higher power levels for write operations than for read operations. High-power-level operations lower the useful life of the laser. Lasers in products used for backup of higher-speed magnetic disks primarily write, and the probability that the useful life exceeds five years is 0.0106. Lasers that are in products that are used for main storage spend approximately an equal amount of time reading and writing, and the probability that the useful life does not exceed five years is 0.5847. Now, 0.7486 of the products from a manufacturer are used for backup, while the remaining manufacturer's products are used for main storage. What is the probability that a laser that failed before five years came from a product used for backup? Select one: O a. 0.87645253 b. 0.01780615 c. 1.07899181 d. 0.83440299
