Back in April and May of 1985, the Gallup organization conducted a poll to estimate the

percentage of Americans who approved of how President Reagan was handling his job.

At the 5% significance level, do the data suggest that the percentage of those who

approved of Reagan increased from April to May in 1985?

Population 1: April p = 795/1528 = 0.5203

Population 2: May p = 840/1528 = 0.5497
