Suppose that we've decided to test Clara, who works at the Psychic Center, to see if she really has psychic abilities. While talking to her on the phone, we'll thoroughly shuffle a standard deck of 52 cards (which is made up of 13 hearts, 13 spades, 13 diamonds, and 13 clubs) and draw one card at random. We'll ask Clara to name the suit (heart, spade, diamond, or club) of the card we drew. After getting her guess, we'll return...

Suppose a fellow female student, Claire Voyant, claims she is a psychic and has extra- sensory perception (ESP). You test her abilities with a deck of cards and a hypothesis test. Holding a card up, that she cannot see, you ask her to guess the correct suit (hearts, diamonds, spades, or clubs) of that card. Now anybody should be able to guess correctly 25% of the time. Based on 100 cards tested, however, Claire got 32 correct answers. Is there...

JAVAFX ONLY PROGRAM!!!!! SORTING WITH NESTED CLASSES AND LAMBDA EXPRESSIONS. DIRECTIONS ARE BELOW: DIRECTIONS: The main point of the exercise is to demonstrate your ability to use various types of nested classes. Of course, sorting is important as well, but you don’t really need to do much more than create the class that does the comparison. In general, I like giving you some latitude in how you design and implement your projects. However, for this assignment, each piece is very...
