A math test was given to five randomly selected schools. The result of the exams is given in the following table.
School 1: 72 83 92 97 82 75 68 93
School 2: 75 81 95 92 88 70 70 90 97 84 76
School 3: 82 73 99 90 66 77
School 4: 71 85 91 95 89 73 70 96 92 83 71 58 63 89
School 5: 82 85 79 90 86 77 71 86 90 73 81 75
Table 1: High School Math Contest
At α = 0.10 level of significance, test the claim that different schools have different mean of math scores on this contest by using the data in table 1. Use non-statistical terminology to state your final conclusion.
Homework Answers
Here we need to compare more than two population means so one way ANOVA will be used.
Hypotheses are:
H0: The different schools do not have different mean of math scores.
Ha: The different schools have different mean of math scores.
Following is the output of one way ANOVA:
The p-value is 0.9563
Since p-value is greater than 0.10 so we fail to reject the null hypothesis.
That is we cannot conclude that different schools have different mean of math scores.

Mean, SD, and the tolerance levels for both for which there would
be any outliers (i.e., the value for which a score must be less

must greater than to be considered an outlier.
