Q6Females had the higher mean score in English. The difference is significant (p-value = 0.024)7. Q7 The correlation co-efficient = -0.2072. As behavior referral increases, there is a drop in performance in English8. Q8= 0.18339. Q9Whites perform better in English as compared to other races and have the highest mean score among the 5 race categories. The mean score for whites in English MCAS is 241.6 and is followed by Asians with a mean of 235.2. Blacks, Hispanics, and Other races are closely tied at 224.85, 224.13, and 223 respectively. This is shown below:RaceMeanStd. DevAsian235.23.666061Black224.84621.504489Hispanic224.1251.329958Other22310.34408White241.66.79411510. Q.10 The hypothesis is that race affect a studentâ€™s performance in English exams. This is the null hypothesis. The alternative hypothesis is that the differences in group means is not significant.We use ANOVA to test this hypothesis:From the analysis, we obtain a p-value or 0.0025 and hence conclude that performance in English is affected by race.
