In 2016, the Pew Research Center surveyed 1,799 white and 1,001 black Americans about their views on race and inequality. Pew researchers found “profound differences between black and white adults in their views on racial discrimination, barriers to black progress and the prospects for change.” White and black respondents also disagreed about the best methods to achieve racial equality. For example, 34% of whites and 41% of blacks said that “bringing people of different racial backgrounds together to talk about...

In a survey of 1000 US adults, twenty percent say they never exercise. This is the highest level seen in five years. a) Verify that the sample is large enough to use the normal distribution to find a confidence interval for the proportion of Americans who never exercise. (Are the conditions met?) Use a formula to justify your answer or, if possible, explain your reasoning.             b) Construct a 90% confidence interval for the proportion of U.S. adults who never...

In 2013, the Pew Research Foundation reported that 45% of U.S. adults report that they live with one or more chronic conditions". However, this value was based on a sample, so it may not be a perfect estimate for the population parameter of interest on its own. The study reported a standard error of about 1.2%, and a normal model may reasonably be used in this setting. The 95% condence interval for the proportion of U.S. adults who live with...
