Sam's psychology professor, Dr. Smith, recruited him to serve as a research assistant. Sam's job was to teach study participants a new strategy for studying textbook material. Experimental group participants were supposed to be taught the new strategy, while control group participants were to be told that they could increase their test scores by holding their textbooks at a particular angle when reading. Each group was allowed to practice the techniques they were taught on a chapter in a psychology textbook, after which Sam tested them over what they had studied.

If so, what was the placebo? c. What term refers to the outcome of Dr. Smith's study? d. Would it be correct to conclude that the procedure that was taught to the control group is a useful study strategy? If not, what is the correct conclusion?

answer in java. Write a class named TestScores. The class constructor should accept an array of test scores as its argument. You will need to do a deep copy of the array, don’t just copy the address of the array. The class should have a method that returns the average of the test scores. If any test score in the array is negative or greater than 100, the class should throw an IllegalArgumentException. Write an exception class named InvalidTestScore. Create a setScores() method in TestScores which accepts an array of test scores. Validate each item in the array and if any test score in the array is negative or greater than 100, the class should throw an InvalidTestScore Exception. Next create another method in TestScore called getScoresFromFile(). This method should open a file that you created in Notepad and it should contain a list of test scores, some valid and others not. Read in each of these test scores and store into an array. The first entry in the file should be the number of scores that should be read. This number should be used to properly create the test score array. The method should properly handle the potential FileNotFoundException. If file does not exist the program should stop and exit with your own error message. As each score is read from the file (use nextInt()) throw either an IllegalArgumentException or an InvalidTestScore if the number read is not between 1 and 100 inclusive. You also need to handle an InputMismatchException. This means that either a string was encountered or a floating-point number was encountered while reading the file. When this happens issue an error message, but continue processing the file until you reach end of file. Note: When this happens the entry you will add to the test score array will contain 0. How you accomplish this is up to you. Feel free to discuss with your instructor. Demonstrate all this functionality in a main() program
