Which one of the following statements is a true statement? O If f:A » B and g:B → C are functions and g o f is one-to-one, g must be one-to-one. O If f:A – » B and g:B → C are functions and g o f is onto, f must be onto. O If f:A → B and g:B » C are functions and gof is one-to-one, f must be one-to-one. O If f:A → B and g:B - → C are functions and g • f is one-to-one, f must be onto.

An SAT prep course claims to improve the test score of students. The table below shows the scores for seven students the first two times they took the verbal SAT. Before taking the SAT for the second time, each student took a course to try to improve his or her verbal SAT scores. Do these results support the claim that the SAT prep course improves the students' verbal SAT scores? Let d = (verbal SAT scores prior to taking the prep course)-(verbal SAT scores after taking the prep course). Use a significance level of a = 0.01 for the test. Assume that the verbal SAT scores are normally distributed for the population of students both before and after taking the SAT prep course. 1 234567 520 570 540 380 370 490 450 Student Score on first SAT Score on second SAT 540 600 610 470 410 510 480 Step 1 of 5: State the null and alternative hypotheses for the test.

Please do this short answer question correctly We are going to roll 5 independent dice (like playing Yahtzee - but we will only roll once). The sum of the values of the dice can range anywhere from 5 (a roll of all 5 dice being a 1) to 30 (a roll of all 5 dice being a 6). I have determined that (to the 6th decimal) P(sum of values of the dice ≥ 8) = .997299. (i) Determine the P(sum of values of the dice ≤ 7) (to the 6th decimal). (ii) Provide a brief explanation as to the reason why your answer is correct.
