One way ANOVA
The null and alternative hypothesis for this one way ANOVA is given as below:
Null hypothesis: H0: There is no significant difference in the averages of the scores for the quizzes, exams and final only.
Alternative hypothesis: There is a significance difference in the averages of the scores for the quizzes, exams and final only.
The ANOVA table with calculations can be seen in the attached images below:
In the attached image below, we get the p-value for this one way ANOVA test as 0.0221. We do not reject the null hypothesis if the p-value is greater than the given level of significance and we reject the null hypothesis if the p-value is less than the given level of significance or alpha value.
In the attached image below, we are given that the p-value = 0.0221 and level of significance or alpha value = 0.05, that is p-value is less than the given level of significance. So, we reject the null hypothesis that there is no significant difference in the averages of the scores for the quizzes, exams and final only. This means we conclude that there is a significance difference in the averages of the scores for the quizzes, exams and final only.
Answer:

Answer: 4
Step-by-step explanation:
1. Subtract 2 from both sides.
5y=22 -2
This equals 5y=20
2.Divide by 5 on each side. That gets 4.
Hope it helped :)
Answer:
c. 3/a
Step-by-step explanation:
5ax + 3ax = 4xa+ 12, combine like terms
8ax = 4ax + 12, minus 4ax on both sides
4ax = 12, divide 4a on both sides
youll be left with x = 3/a
