Along with the new sample obtained from the moon of Terra Australis, the mission team brought back a hologram of a killer drop bear. When you took a glance, a weird idea crossed your mind. Is it possible that the killer drop bears are actually koalas? You started searching for information and found a paper published 800 years ago. The paper claimed the joy of koalas has dropped a lot in the last decade, saying "5 out of the 20 lasted groups of koalas have been shown to be joyless". They have classified a koala group as "joyless" if they have a an average joy score under 4. Test the hypothesis that the probability of a "joyless" group of killer drop bears is equal to the probability of a "joyless" group of koalas. Please convert the sample of average joy values .S, in question 1 to binary data with a threshold of 4, test the hypothesis, and interpret the p-value
