Researchers created two test sheets, each sheet showing 20 photos of the faces of dog-owner pairs. The two sheets wereequivalent with respect to breed, diversity of appearance, and gender of owners. On the first sheet the dogs were matchedwith their owners, while on the second sheet the dogs and owners were deliberately mismatched. Three experiments wereconducted, and in all experiments, subjects were asked to "choose the set of dog-owner pairs that resemble each other,Sheet 1 or Sheet 2," and were simply told the aim of the research was a "survey on dog-owner relationships." In the firstexperiment, the original sheets were shown to subjects; in the second experiment, just the mouth region of the ownerswas blacked out in all the pictures on both sheets; while in the third experiment, just the "eye region" of the owners wasblacked out. Subjects were assigned at random to the three experimental groups, and in each experiment, the number ofsubjects who selected the sheet with the dogs and their owners correctly matched was recorded. Experimenters wereinterested in whether blacking out portions of the faced reduced the ability of subjects to correctly match dogs andowners.

I understand how the level of signficance = 1.96 and I understand: Ho:μ=5 - Ha:μ<5 But I need help understanding how to calculate the test statistic. I know we have a sum of 93 with a sample size of 28 but how do you come to the conclusion for the test stastisic and how do you figure out whether you have enough proof to accept or reject the claim? Thank you.
