Answer the following about T-Test & T-distributions: 1. Which of the following statements related to the t-distribution is not true? Select one: a. Since the population standard deviation is usually unknown, the standard error of the sample mean is estimated using the sample standard deviation as an estimator for the population standard deviation. The formula is s/sqrt(n). b. The population must be t-distributed in order to use the t-distribution. c. Like the Normal distribution, the t-distribution is symmetric and unimodal....

Determine if the statements below are true or false: The chi-square distribution, just like the normal distribution, has two parameters, mean and standard deviation. The chi-square distribution is always right skewed, regardless of the value of the degrees of freedom parameter. The chi-square statistic is always positive. As the degrees of freedom increases, the shape of the chi-square distribution becomes more skewed. "If you found χ2 = 10 with df = 5, you would fail to reject the Null hypothesis...
