Question
In February 2021, Pew Research asked 2,596 random US adults what gives them meaning in life. 17% of respondents said, "occupation and
career. We know that the proportion of the sample who answer "occupation and career" will vary in repeated sampling. In repeated sampling, the
sample proportion, p-hat, has an approximately normal distribution with mean 0.17 and standard deviation 0.007. Use this information to answer
the questions below. Show your work for each question and round all numeric answers to 3 decimal places.
