To tackle the hypothesis that the proportion
In testing, it’s crucial to remember that a right-tailed test evaluates whether the sample data provides sufficient evidence to support the claim that the population proportion is greater than a specified value (in this case, 0.59). This means all of our statistical significance will be concentrated in one direction, which simplifies both our calculations and interpretations!
