This is the question

Are people born in certain seasons more likely to be allergic to dust mites? Research suggests this might be true. The table below gives the birth seasons of 500 randomly selected people who are allergic to dust mites, along with the proportion of births in the general population for each season. Do these data provide convincing evidence that the distribution of birth season is different for people who suffer from this allergy? Number of allergy Proportion of births in Birth Season sufferers general population Winter 117 0.30 Spring 105 0.22 Summer 145 0.24 Fall 133 0.24
