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.
Answer:
a(-2.6) b(5, 0) c(9,5)
Step-by-step explanation:
the rule is x+1 y+2 for each of the vertices
Answer:
Step-by-step explanation:
x = City Roast Colombian coffee
y = French Roast Colombian coffee
x + y = 20
The common difference is 19-7 = 31-19 = 12, so this is an arithmetic sequence. The initial term (when n=1) is 7.
The explicit formula for the terms of an arithmetic sequence is
an = a1 + d(n-1)
where "a1" is the first term and "d" is the common difference. The formula that matches a1=7 and d=12 is
B. a(n) = 7+(n-1)·12
