What conclusion can be drawn? Reject Ho, there is no evidence that electrical stimulation helps. O Do not reject Ho, there is no evidence that electrical stimulation helps. O Reject Ho, there is evidence that electrical stimulation helps. Do not reject Hn, there is evidence that electrical stimulation helps. Can we conclude that electrical stimulation of the brain helps people solve a new problem that needs fresh insight? Yes, because the results are significant. O No, because the results are not significant. Yes, because the results come from an experiment. O No, because this was an observational study not an experiment. O Yes, because the results come from an experiment and they are significant.

Question

We introduce a study in which participants are trained to solve problems in a certain way and then asked to solve an unfamiliar problem that requires fresh insight. Half of the participants were randomly assigned to receive electrical stimulation of the brain while the other half (control group) received sham stimulation as a placebo. The results are shown in Table 1.

A.)What is the sample statistic?

sample statistic=?(exact number)
