In this study, the college instructor aims to know whether there are differences in the performance of students among the three classroom environments. We consider the _______________. as the factor variable. Also, the response variable is the _____________. which is in the ___________________. level of measurement. The students were independently and randomly assigned to each of the three classroom environments: Mozart piece, relaxation music, and silence. The p-values obtained from the Shapiro-Wilk test indicate that the assumption of ________________. was ___________________. Further, results obtained from the Levene’s test indicate that the assumption of _______________ was ________________. Considering the variable of interest and the results of the test for the assumptions, the appropriate test procedure to analyze the given data is the ________________ The appropriate set of hypotheses to test the given objective is Ho: _____________and Ha: _________________.

D The chances of winning are often written in terms of odds rather than probabilities. The odds of winning is the ratio of the number of successful outcomes to the number of unsuccessful outcomes. The odds of losing is the ratio of the number of unsuccessful outcomes to the number of successful outcomes. For example, if the number of successful outcomes is 2 and the number of 2 unsuccessful outcomes is 3, the odds of winning are 2:3 (read "2 to 3") or.
