A company has released its new phone which is available in 4 capacity models: 32GB, 64GB, 128GB, and 256GB. A store has sold 284 phones over the last week: 63 phones of the 32GB model, 73 phones of the 64GB model, 77 of the 128GB model, and 71 of the 256GB model. We will use the chi-square goodness-of-fit test to asses whether the four models’ total sales are significantly different from one another.
