It is said that 85% of NFL players will have a “short” career of less than 5 seasons. Of the 1696 players in the NFL, 1476 of them have been playing for less than 5 years. Is the actual proportion likely to be higher than 85%? State a maximum confidence level.

Solutions

Expert Solution

The maximum confidence level is 99%

Therefore, 99% confidence interval for population proportion is (0.849, 0.891)

NO, the actual proportion is likely to be not higher than 85% since 85% is in the above interval

A recent national survey stated 70% of college students said they get less than the recommended amount of sleep every night. A statistician decides to test this claim against the suspicion that the percentage is too high. The statistician randomly sampled 1500 college students from the population of college students and determines that 1020 college students stated they don’t get the recommended amount of sleep. Perform a hypothesis test to answer the question: Do the sample results support the statistician’s...

Suppose we are interested in analyzing the weights of NFL players. We know that on average, NFL players weigh 247 pounds with a population standard deviation of 47 pounds. Suppose we take a sample of 30 new players and we find that the average weight from that sample is 237 pounds. We are interested in seeing if the weight of NFL players is decreasing. Show work. What is the standard error? What is the margin of error at 90% confidence?...
