... (1.39, 4.01) We are 95% certain that the true difference between the computer and driver measurements is in the calculated interval. Since the difference was calculated as computer – driver, the postive values suggest that the drivers calculation is on average lower than the computers calcuation; th ...

... Part 1: Construct a 98% confidence interval estimate for the mean pH levels of rain in that area for the year 2000. Part 2: At the 1% significance level, test the claim of the biologist that the pH level of the rain in that area has decreased, and therefore, the acidity of the rain has increased. Pr ...

... If the difference is not equal to zero, do we reject the null hypothesis? To answer that question we need to know what chance or random error can do—what kind of differences is chance likely to produce? The central limit theorem provides a distribution based on chance. This allows us to see how chan ...

... Example: Testing μ with a Small Sample A used car dealer says that the mean price of a 2005 Honda Pilot LX is at least $23,900.You suspect this claim is incorrect and find that a random sample of 14 similar vehicles has a mean price of $23,000 and a standard deviation of $1113. Is there enough evid ...
