1. Perform a One Factor Analysis of Variance (ANOVA) using SPSS comparing the mean gestation values for the three brain_type groups at an alpha of 0.05.
2. What is the null hypothesis for this ANOVA:
3. Calculate the mean of each of the 3 groups:
   1. Mean of small group ______________
   2. Mean of medium group ______________
   3. Mean of large group _______________

1. alpha: ________________
2. F test statistic: ________________
3. p-value: ________________
4. Paste a screenshot of your ANOVA result from your software below

2. Based on the results:

1. Would you reject or fail to reject the null hypothesis?
2. Provide your interpretation of the results of the ANOVA.
