Suppose Nathan, an avid baseball card collector, is interested
in studying the proportions of common, uncommon, and rare 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,
15% are uncommon, and 10% are rare. Nathan wishes to test the
validity of this claimed distribution, so he randomly selects 20
packs of baseball...

Your friend has been collecting baseball cards. The company
claims that you should have a 60% chance of finding a normal card,
a 30% chance of finding an uncommon card, and a 10% chance of
finding a rare card. Your friend has been opening packs of cards
and collected 50 cards: 35 normal, 14 uncommon, and only 1 rare
card.

1)Employers want to know which days of the week employees are
absent in a five-day work week. Most employers would like to
believe that employees are absent equally during the week. Suppose
a random sample of 71 managers were asked on which day of the week
they had the highest number of employee absences. The results were
distributed as in Table. For the population of employees, do the
days for the highest number of absences occur with equal
frequencies during...
