in a recent pew research poll, adult men and women in the u.s. were asked to identify egypt when is was highlighted on a map of the middle east. 279 out of 532 randomly selected men were able to identify egypt, while 217 out of 512 randomly selected women were able to identify egypt. is this convincing evidence that there is a difference between the proportion of all adult men in the us that can identify egypt on a map and the proportion of all adult women in the us that can identify egypt on a map?
