Teachers want to know which night each week their students are doing most of their homework. Most teachers think that students do homework equally throughout the week. Suppose a random sample of students were collected which shows that the Number of students doing their homework on SUN where 16 Number of students doing their homework on MON where 18 Number of students doing their homework on TUE where 12 Number of students doing their homework on WED where 18 Number of students doing their homework on THR where 8 Number of students doing their homework on FRI where 4 Number of students doing their homework on SAT where 3 What is the Test Statistics to test the Hull Hypothesis that students were doing their homework with equal frequencies (that is, they fit a uniform distribution) against the alternative Hypothesis that students prefer doing their homework on a particular day (that is, they do not fit a uniform distribution)?

There is a game  pick beads from a jar 2 blues and 1 purple, if someone picks  blue bead they roll 2 dice and add the outcomes, if a player chooses a purple bead then you roll 2 dice and then multiply the outcomes together. A1 is the event of  scoring 1 A2 have a score of 2 let V  be probability of selecting blue bead Let  Sbe probability  of selecting purple bead   Draw out a probability tree and answer following Find P(A10).   1.  Find P(A12 ∩ V)   .  Find P(A12|S).    Use definition of independent events whether the events A5 and V are independent or not.   ( Use  definition of independent events to show whether the events A4 and S are inde. or not please explain reasoning
