Of the 373 people from the inner city surveyed, 48 of them suffered from sleep apnea. What can be concluded at the level of significance of a = 0.05? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? vSelect an answer (please enter a decimal) H1: ? v Select an answer V (Please enter a decimal) c. The test statistic ? v (please show your answer to 3 decimal places.)

Your job is to determine if sample (the Miami Heat) differs from the whole population (the whole NBA). In other words, are the players on the Miami Heat representative of the rest of the NBA in terms of points per game? What is the null and alternative hypothesis?
