A bootstrap distribution for this data is shown.

Find a 90% confidence interval for the proportion of all Americans who believe there is solid evidence of global warming. (Show all work!) (3 points) (Hint: Sample statistic + z* SE. The SE is found on the top right of the distribution.) g. Use a clear, complete sentence to interpret the confidence interval found in f. (3 points)
