Question
Babies and younger boys are more likely to be diagnosed with peanut allergies. To test this claim a group of researchers tested the allergies among a group of boys and girls aged below 18 years.
A total of 540 kids were selected randomly and asked to eat a small amount of peanut.
Group | n | x |
Boys | 280 | 120 |
Girls | 260 | 90 |
Do boys have a higher chance to be diagnosed with a peanut allergy?
Calculate the test statistic.
Calculate p-value.
