Answer:
Because P<a, there is significant evidence against the claimed distribution of baseball cards.
When a=0.05, and P<a, we reject the null hypothesis and say that the result is statistically significant.

stion 2 of 10> Suppose Nathan, an avid baseball card collector, is interested in studying the proportions of common, uncommon, and rar baseball cards found in newly purchased card packs. Each card pack contains exactly 10 baseball cards. The fine print on each pack of cards says that, on average, 75% of the cards in each pack are common, 20% are uncommon, and 5% are rare. Nathan wishes to test the validity of this claimed distribution, so he randomly selects...
