1. 240 males out of 500 total people, probability of picking a male is 240/500 = 12/25

2. P(female) = 260 / 500 = 13 / 25

3. P(she does not) = P(no | female) = P(female and no) / P(female) = 36 / 260

4. P(yes) = 360 / 500

5. P(male and yes) = 136 / 500

6. use a chi square test: you’ll find a p-value of 2.2 * 10 ^ -6, so the rows are not independent.

Having taken a quantity of school degree data guides, I could generally tend to impeach any statistical outcome published at any place. There are such a lot of vairables that for probably the most aspect, data are inappropriate in serving as a correct predictor of so much of whatever. BB, Raji the Green Witch
