7. One of the most pressing problems in high-technology industries is computer-security. Computer security is typically achieved by a password a collection of symbols (usually letters and numbers) that must be supplied by the user before the computer system permits access to the account. The problem is that persistent hackers can create programs that enter millions of combinations of symbols into a target system until the correct password is found. The newest systems solve this problem by requiring authorized users to identify themselves by unique body characteristics. For example, system developed by Palmguard, Inc. tests the hypothesis H0: The proposed user is authorized VBI'SUS H1: The proposed user is unauthorized. by checking characteristics of the proposed user's palm against those stored in the authorized users' data bank (0mm, 1.984). a) Dene a Type I error and a Type II error for this test. Which is the more serious error? Why? b) Palmguard reports that the Type I error rate for its system is less than 1% where as the Type II error rate is .00025%. Interpret these error rates. c) Another successful security system, the EyeDentifyer, \"spots autho- rized computer users by reading the one-of-a-kind patterns formed by the network of minute blood vessels across the retina at the back of the eye.\" The EyeDentier reports Type I and Type II error rates of 01% (1 in 10,000) and 005% (5 in 100,000), respectively. Interpret these rates
