Answer:
The critical value of F for this situation is 2.975.
Step-by-step explanation:
A test is being performed to determine if a particular drug, smartozine, affects maze learning in rats.
The groups are divided as follows:
- Three groups of 8 rats each are injected with one of three different doses of smartozine.
- The fourth group of 6 rats is injected with a saline solution as a control.
So, there were in total <em>k</em> = 4 groups with <em>n</em> = 30 rats.
The significance level of the test is, <em>α</em> = 0.05.
Compute the critical value of <em>F</em> as follows:
*Use the <em>F</em>-table.
Thus, the critical value of F for this situation is 2.975.
