- If there is no seasonal effect on human births, we would expect equal numbers of children to be born in each season (winter, spring, summer, and fall). A student takes a census of her statistics class and finds that of the 120 students in the class, 24 were born in winter, 36 in spring, 32 in summer, and 28 in fall. She wonders if the excess in the spring is an indication that births are not uniform throughout the year. Complete parts a through c below. Question content area bottom Part 1 a) Compute the standardized residual for each season. Standardized Residual Winter Spring Summer Fallصورة من Sora AlsaadAlpesh
