I need help with the following:

1. Which ones are the dependent/independent variable and its levels?
2. what analysis was used?
3. What is the probability of a Type I error (i.e., alpha level)?
4. What is the omnibus ANOVA?
5. was a post hoc test used?
6. What is the sample size, mean and standard deviation for each condition?
7. What are the all differences for the variables examined?
8. What is the effect size?

ll. Th5 endorphins released by the brain act as natural painkillers. Fa: example. Cinder { I970) mtmitored endorphin actiVity and pain thresholds in pregnant rats during the days before they gave birth. The data showed an increase in pain threshold as the pregnancy pm} gressad. The change was gradual until 1 or 2 days before binh, at which point there was an abrupt increase in pain threshold. Apparently a natural painkilling mechanism was preparing the animals for the stress of giving birth. The following data represent pain-timhold 500m similar to the results obtained by Gintzler. Do these data indicate a signicant change in pain threshold? Us: a repeated-measures ANOVA with a = .01.
