1) For the first question, the appropriate statistic to use is "p-hat" since we are calculating the proportion of Americans who agree with the policies of the current president.
2) To find the value of p-hat, we divide the number of yes answers (1,789) by the total number of respondents (5,000):
p-hat = 1,789 / 5,000
The value of the appropriate statistic is p-hat = 0.3578 (rounded to four decimal places).

1) For the second question, the appropriate statistic to use is also "p-hat" since we are calculating the proportion of seniors who agree with the current late work policy.
2) To find the value of p-hat, we divide the number of yes answers (165) by the total number of respondents (212):
p-hat = 165 / 212
The value of the appropriate statistic is p-hat = 0.7783 (rounded to four decimal places).
