Write a program called ForLoopPractice that • prompts the user for a maximum value and uses a for loop to output all even numbers between 0 and the maximum value, one per line. • prompts the user for a first and last value and uses a for loop to output all integers between the first value and the last value, one per line. If the user enters a value that cannot be read as an int, the program should print "Invalid value" and exit. HINT: The statement, System.exit(1), will cause your program to exit. Here are some examples of program execution: $ java ForLoopPractice Print even values Max Value: 9 0 2 4 6 8 Print a range of values First Value: 9 Last Value: 4 9 8 7 6 5 4 $ java ForLoopPractice Print even values Max Value: -4 Print a range of values First Value: 2 Last Value: 3 2 3 $ java ForLoopPractice Print even values Max Value: 4 0 2 4 Print a range of values First Value: abc Invalid value

4. There are 36 students, each of whom submitted an examination paper. On the basis of years of experience, the grader knows that the time needed to grade a randomly chosen examination paper is a random variable with an expected value of 5 minutes and a standard deviation of 5 minutes. a.) If grading times are independent and the grader begins grading at 5:50 P.M. and grades continuously, what is the probability that he finishes grading before a 9:00 P.M. TV show? b.) This year's problems look quite different from previous years', so you are unsure about the average time for grading each paper. (Suppose the standard deviation for each paper is still 5 minutes). If in this year the grader finishes grading at 9:30 PM, construct a 95% confidence interval for the population mean (for individual grading time). c.) Based on information in b.) Do you think this year's exam, in terms of grading time, is similar to the previous years? Provide formal argument to support your statement.

3. 7.3.12 Professor T. R. S. Eighty proposes the following version of binary search: 1. binary - search2(s, i, j, key) 2. if (i > j) 3. return 0 4. k = ?(i + j)/2? 5. if (key == s_k) 6. return k 7. k1 = binary - search2(s, i, k - 1, key) 8. k2 = binary - search2(s, k + 1, j, key) 9. return k1 + k2 (a) (5 pts) Show that binary - search2 is correct; that is, if key is present, the algorithm returns its index, but if key is not present, it returns 0. (b) (5 pts) Find the worst case running time of binary-search2.
