# Week 5 Biostatcies

I need support with this Statistics question so I can learn better.

### Week 5 Assignment: Hypothesis Testing (continued)  Open the small Excel database that was provided to you in week 4. To run the test statistics you have to re-arrange your data.

With this database, you will:

1. Run a one-way ANOVA to compare three or more groups of people (specified by a categorical variable) on one continuous variable.
1. Write the null and alternate hypotheses.
2. What is the calculated mean for each group?
3. What is the calculated F value?
4. What is the p and critical F value?
5. Is the p value significant? Is calculated F value greater than Critical F value? Conclusion?
2. Run a chi-squared test to determine whether one group of people has higher rates of a given outcome relative to the other groups of people in the data set.
1. Write the null and alternate hypotheses.
2. What is the calculated chi-square value?
3. What is the p and critical value?
4. Is the p value significant? Is calculated chi-square value greater than Critical F value? Conclusion?
