Emma's On-the-Go, a large convenience store that makes a good deal of money from magazine sales, has three possible locations in the store for its magazine rack: in the front of the store (to attract "impulse buying" by all customers), on the left-hand side of the store (to attract teenagers who are on that side of the store looking at the candy and soda), and in the back of the store (to attract the adults searching through the alcohol cases). The manager at Emma's experiments over the course of several months by rotating the magazine rack among the three locations, choosing a sample of 41 days at each location. Each day, the manager records the amount of money brought in from the sale of magazines. Below are the sample mean daily sales (in dollars) for each of the locations, as well as the sample variances: Sample Sample Sample size Group mean variance Front 41 218.0 365.0 Left-hand side 41 211.1 602.5 Right-hand side 41 211.1 415.3 Send data to calculator Send data to Excel Suppose that we were to perform a one-way, independent-samples ANOVA test to decide if there is a significant difference in the mean daily sales among the three locations. Answer the following, carrying your intermediate computations to at least three decimal places and rounding your responses to at least one decimal place. (a) What is the value of the mean square for error (the "within groups" mean square) that would be reported in the ANOVA |I test? (b) What is the value of the mean square for treatments (the "between groups" mean square) that would be reported in the|| ANOVA test?

jared is opening several ice cream stores. The walls of the stores can be yellow or blue. He wants to determine if the color of the walls affects how much ice cream people eat. Jared finds 164 volunteers. He randomly assigns half of them to a room with yellow walls and lets them eat as much chocolate ice cream as they want for one hour. He assigns the other half to a room with blue walls and lets them eat as much vanilla ice cream as they want for two hours. Jared records the total amount of ice cream eaten in each room.Which would be an appropriate statistical model for Jared to use in order to determine if the color of the wall affects how much ice cream his customer will eat?

Sessa, an ancient wise man, visited the king of his nation and showed him a new game.  The board was 8 squares by 8 squares.  Two players would be given 16 pieces each, lined up on either side of the board.  The pieces moved in set ways, and the purpose of the game was to move your pieces to trap the King piece of the other player. As you have probably figured out, Sessa invented chess. His king was utterly delighted at the game - war without bloodshed! - and asked Sessa what he would like in return.  In the ancient bombastic style, the King said the request could include up to half of his kingdom.  (That was not meant literally.)  Sessa asked for the game board to be brought before him. "Highness," he said, "I ask for a grain of rice on the first square.  Tomorrow, two grains of rice on the second square.  The day after, 4 grains of rice on the third square.  On the fourth day, 8 grains of rice.  And so on, until the board is full in two months." The king and his ministers laughed…
