A group of APAP Chemistry students debated which fast-food chain had better quality bags, Fast Food Chain W or Fast Food Chain M . They decided to investigate by selecting a random sample of 25 bags from each fast food restaurant, slowly adding water until each bag began to leak, and recording the volume of water they were able to pour into each bag. They then calculated the mean volume and standard deviation, in ounces, for the two types of bags. Which of the following are the correct null and alternative hypotheses to test whether the mean volume of water the bags from Fast Food Chain W can hold without leaking, μWμW, is different from that for the bags from Fast Food Chain M, μMμM ? A. H0:μW−μM=0Ha:μW−μM>0H0:μW−μM=0Ha :μW−μM>0
B. H0:μW−μM<0Ha:μW−μM>0H0:μW−μM& lt;0Ha:μW−μM>0
C. H0:μW−μM=0Ha:μW−μM≠0H0:μW−μM=0Ha:μW −μM≠0
D. H0:x¯W−x¯M=0Ha:x¯W−x¯M>0H0:x¯W−x ¯M=0Ha:x¯W−x¯M>0
E. H0:μW−μM=0Ha:μW−μM<0H0:μW−μM=0Ha :μW−μM<0

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
