In this case the test statistic T is the sample mean. Under the null hypothesis it has a mean of 100 and a standard deviation of 20/sqrt(N). First let's look at a fixed sample size, say N=16. We will reject the null hypothesis if T is in the shaded region, which is the upper...
This study aims to fill the gap by proposing a novel joint neural network model that can naturally fit both static and sequential user data. To evaluate the effectiveness of the proposed method, this study take the problem of at-risk student prediction as an example where both static data (...
The number of overweight people around the world is increasing. For example, in Chin a the number rose from 9 percent to 15 percent between 1989 and 1992. The increases in Latin Americ a and Europe were similar. However, the most worrying statistic is the increase in the number of overweig...
Give an example of inferential statistics.Answer and Explanation: Whenever you measure a part of a population, and estimate some value about the rest of the population, you are using inferential stastics. A phone survey would be a good example of inferential statistics....

Thet-statistic for the beta estimate of GOOG is now significant at the 99.5% level of significance. Note, however, that thet-statistics for beta estimates are based on standard errors from the sample Hessian which, in contrast to the Fisher information matrix, accounts for the increased uncerta...
