D You have been studying spatial learning in rats and you suspect that a particular gene, which you call the SPR gene, has an effect on spatial reasoning. You block this gene in a random sample of 36 rats and test their performance in a maze. The rats in your sample take an average of 88 seconds to complete the maze, with a standard deviation of s = 15. The mean time to complete the maze among normal rats of this subspecies is 80 seconds. Calculate the appropriate obtained test statistic (z or t): Please show your work. Edit View Insert Format Tools Table Assuming a .01, to what critical value(s) should you compare your test statistic
