Is this right?

7. (3 points) A baseball card company states that, on average, a pack of cards should contain 30% rookies, 50% non-all star veterans, and 20% veteran all-stars. You purchase a few packs, with a total of 160 cards, and find that you have 40 rookies, 96 non-all star veterans, and 24 veteran all-stars. Does your data differ significantly, at a = 0.05, from the company's claim? H.: The pack of cards distribution matches baseball card company claim H1: The distribution is different from the claim X crit = 5. 99 15 + *2 samp = 6. 5 3 3 3 We reject Ho; There is strong statistical evidence that our pack of Carts was either not produced at random from all pack of cards or that the claim made by baseball card company about their distribution is incorrect
