Question

Researchers conducted a study investigating the number of viral
infections people contracted as a function of their stress over a 6-month period. Use the provided steps to conduct a one-factor between-subjects ANOVA that test whether there are any differences in number of infections across the four conditions.
a. State the hypotheses. 


b. Determine the critical value for an alpha level of 0.05.

### Stress Category Data This table categorizes stress into four levels: Negligible, Minimal, Moderate, and Severe. Each category contains numerical values representing some form of data points. Below the data points, the table provides the mean (\(M\)) and standard deviation (\(S\)) for each stress category. #### Data Points - **Negligible Stress** - Values: 1, 2, 2, 1 - Mean (\(M\)): 1.50 - Standard Deviation (\(S\)): 0.58 - **Minimal Stress** - Values: 2, 1, 1, 1 - Mean (\(M\)): 1.25 - Standard Deviation (\(S\)): 0.50 - **Moderate Stress** - Values: 3, 3, 3, 4 - Mean (\(M\)): 3.25 - Standard Deviation (\(S\)): 0.50 - **Severe Stress** - Values: 3, 4, 4, 3 - Mean (\(M\)): 3.50 - Standard Deviation (\(S\)): 0.58 This table might be useful for analyzing variations and trends in stress levels across different groups or conditions, as reflected by the calculated mean and standard deviation.
