Stat testing %s between 2 groups

[Labracadabra]

I need some help figuring out how to stat test percentages between two groups
in Excel 2007. Here's an example of my data:

A B C
1 Scores for: Men Women
2 Awareness of product 45% 63%
3 Rate product "excellent" 78% 43%
4 "Definitely" will buy 23% 32%
5 Base size 98 137

I need to know if the scores for men are statistically different from
women's scores. In other words, are the scores in column B different from
column C. It's been ages since I took stats in school, and I just can't
remember! Help!
