32:36 Time Remaining Return Submit Problems 8-13 9 1 point Suppose a psychologist tested if having aging rats live in an What would the critical t-values be for this two-tailed test with a = .05? environmentally stimulating environment helps to keep their memory from declining. Elderly rats were assigned to one of two conditions: a O + 1.796 stimulating environment (n = 5) or a standard laboratory rat O 1.812 environment (n = 7). The rats spent 12 weeks in their assigned environments, after which they learned a complex maze to receive a 2.201 OO food reward. The researcher then compared the average time it took + 2.228 rats housed in the stimulating and standard environments to complete the maze; the longer the time taken, the weaker the memory. Here are the results: 10 1 point Stimulating Environment Group: M = 750 seconds Control Environment Group: M = 865 seconds What is the estimated standard error?
