The inferotemporal cortex (IT) plays an important role in visual object discrimination in human and non-human primates. A researcher knows that macaque monkeys can learn an object discrimination task in 25 trials, on average. The distribution of learning times is normal with a standard deviation of o = 5.8 trials. A surgical intervention makes it possible to deactivate IT temporarily, and the researcher believes that doing so will lead to longer learning times. A random sample of 26 adult male macaques underwent this procedure. Following recovery, the monkeys learned the object discrimination task while I was deactivated, and the mean number of trials to learn the task was m = 32.25 trials. Which of the following is the alternative hypothesis for this scenario?
O μ₁-μ₀=0
O μ₁-μ₀≠0
O μ₁-μ₀<0
O μ₁-μ₀>0
