You would like to check and see if the agar recipe you use has an effect on bacterial growth. You make five plates with agar A and five plates with agar B. You inoculate the plates and incubate them together for 24 hours. You take out the plates and count the colonies on each. You accumulate the following results. Agar A: average number of colonies = 24.52 Standard Deviation for A = 3.34 Agar B: average number of colonies = 18.76 Standard Deviation for B = 4.61 The teale value you calculated is 2.262. What is the value of terit?
