For each of the following statements; on the line preceding the statement, write “T” if you believe the statement is True and “F” if you believe the statement is false.

_____ The calculated value of the test statistic measures how far away the sample statistic is from the hypothesized value of the population parameter.
__T__ Sample statistics can be used to estimate the value of a parameter of a population.
_____ When evaluating the results of a hypothesis test, if the calculated value of the test statistic is greater in magnitude than 1.96; we would reject the null hypothesis at the 95% confidence level.
__F__ sp is used to symbolize the standard error of the mean for a sample.
_____ The symbols μ and π represent sample statistics that are typically the focus of hypothesis testing.
_____ The statement, “The null hypothesis is that the average rating of the population is equal to 4.5.” can be represented by: Ho: μ = 4.5.
_____ Statistics are a summary description of a characteristic of sample.
__T__ The confidence level is described as the range in which the true value of the population parameter will fall.
_____ Ho: π = 40% is an example of an alternate hypothesis.
__T__ A parameter denotes the true value of the sample if a census was undertaken.
