In 1948, Podoloff lured the Lakers, Royals, and two other teams to the BAA and proposed a merger of the two leagues for the 1949–1950 season. The result was the National Basketball Association (NBA), with Podoloff its first missioner. The seventeenteam league struggled at first but soon reduced its size and gained stability, in large part because of Mikan39。s development: zone defenses, the weave, the passing game, and the fast break. In the decade preceding World War II, five events changed college basketball and allowed it to bee a major spectator sport. In 1929, the rules mittee reversed a decision that would have outlawed dribbling and slowed the game considerably. Five years later, promoter Edward Ned Irish staged the first intersectional twin bill in Madison Square Garden in New York City and attracted more than 16,000 fans. He demonstrated the appeal of major college ball and made New York its center. In December 1936, Hank Luisetti of Stanford revealed the virtues of the onehanded shot to an amazed Garden audience and became the first major collegiate star. Soon thereafter, Luisetti scored an incredible fifty points against Duquesne, thus ending the East39。s Philadelphia SPHAs (South Philadelphia Hebrew Association)。s World Basketball Association, before the WNBA debuted in 1997 with the support of the NBA. James Naismith, originally from Almonte, Ontario, invented basketball at the International YMCA Training School in Springfield, Massachusetts, in 1891. The game was first played with peach baskets (hence the name) and a soccer ball and was intended to provide indoor exercise for football players. As a result, it was originally a rough sport. Although ten of Naismith39。s basketball league in the United States was the National Basketball League (NBL), which debuted in 1898. Players were paid on a pergame basis, and this league and others were hurt by the poor quality of games and the everchanging players on a team. After the Great Depression, a new NBL was organized in 1937, and the Basketball Association of America was organized in 1946. The two leagues came to agree that players had to be assigned to teams on a contract basis and that high standards had to govern the game。s basketball. Until World War II, basketball became increasingly popular in the United States especially at the high school and college levels. After World War II, its popularity grew around the world. In the 1980s, interest in the game truly exploded because of television exposure. Broadcast of the NCAA Championship Games began in 1963, and, by the 1980s, cable television was carrying regular season college games and even high school championships in some states. Players like Bill Russell, Wilt Chamberlain, and Lew Alcindor (Kareem AbdulJabbar) became nationally famous at the college level and carried their fans along in their professional basketball careers. The women39。 England in 1894。s five basic principles center on the ball, which was described as large, light, and handled with the hands. Players could not move the ball by running alone, and none of the players was restricted against handling the ball. The playing area was also open to all players, but there was to be no physical contact between players。s games measures in (7576 cm) in circumference, and a women39。所以，x 與 y 非相互獨立。試求產(chǎn)品經(jīng)質(zhì)檢后為合格品的概率，又問一件經(jīng)檢驗為合格品的產(chǎn)品確是合格品的概率是多少？解：設(shè)A 表示任取的一件產(chǎn)品是合格品，B表示任取的一件產(chǎn)品被檢驗為合格品。設(shè)產(chǎn)品的單位成本是200元，售價是500元。 三、計算題（每小題8分，本題共56分）在次品率為5%的一批產(chǎn)品中任取5件，求其中至少有兩件次品的概率。 以下哪一個MATLAB命令用于求定積分。 設(shè)是相互獨立的兩個隨機變量，則。設(shè)正態(tài)總體的均方差，該總體的一個容量為的樣本的樣本均值，則 總體均值的置信水平為95%的置信區(qū)間是或 。 （ 已知標準正態(tài)分布函數(shù)值：）設(shè)隨機變量服從泊松分布且具有方差2，那么的分布律為。試求工廠承擔全部退款的概率以及一件產(chǎn)品的期望利潤。以下是某農(nóng)作物對三種土壤，四種肥料，每一個處理作三次重復試驗后所得產(chǎn)量的方差分析表的部分數(shù)據(jù)，完成方差分析表并寫出分析結(jié)果。 設(shè)總體，對檢驗水平，欲檢驗方差由容量為的一個樣本計算出來的統(tǒng)計量的觀察值應(yīng)與作比較。二維隨機變量的分布函數(shù)。在雙因素有交互作用的方差分析中，設(shè)因素有3個水平，因素有2個水平，每個 處理作兩次重復試驗，則試驗誤差平方和的自由度 。設(shè)一維連續(xù)型隨機變量的概率密度函數(shù)為，則隨機變量的概率密度函數(shù)為 。 （ 已知標準正態(tài)分布函數(shù)值：）設(shè)隨機變量服從泊松分布且具有方差2，那么的分布律為 。設(shè)正態(tài)總體的均方差，該總體的一個容量為的樣本的樣本均值，則 總體均值的置信水平為95%的置信區(qū)間是 。 設(shè)是相互獨立的兩個隨機變
