A physiological psychologist has performed an experiment to determine if a particular drug, smartozine, affects maze learning in

rats. Three groups of 8 rats each are injected with one of three different doses of smartozine, while a fourth group of 6 rats is injected with a saline solution as a control. After the injection, rats in all four groups are timed in how long it takes them to learn to traverse a maze. The results of the experiment are presented below. Did smartozine affect how quickly the rats learned the maze. Use a level of significance of.05 SSB 610 SSW = 1742 What is the critical value of F for this situation?

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:

F_{\alpha, (k-1, n-k)}=F_{0.05, (4-1, 30-4)}=F_{0.05, (3,26)}=2.975

*Use the <em>F</em>-table.

Thus, the critical value of F for this situation is 2.975.

Alex

-5

a^2-25=0

a^2=25

take the square root of both sides

Meryl needs to add enough water to 11 gallons of an 18% detergent solution to make a 12% detergent solution. Which equation can
LenKa [72]
A suitable equation will equate the quantity of detergent both before and after the water is added to the solution.

the amount of detergent in 11 gal of 18% solution is the same as the amount of detergent in the 12% solution (after g gallons of water are added)
  .18*11 = .12*(11+g)
