In R STUDIO

The CEO of a large electric utility claims that 79 percent of his 1,000,000 customers are very satisfied with the service they receive. To test this claim, the local newspaper surveyed 100 customers, using simple random sampling. Among the sampled customers, 73 percent say they are very satisfied. Based on these findings, can we reject the CEO's hypothesis that 79% of the customers are very satisfied? Use a 0.04 level of significance. The CEO changed the claim and now says that at least 79% are satisfied, keeping everything else the same, how does this change your analysis?
