Summary statistics are a subset of descriptive statistics. True False A confidence interval can be used instead of a test statistic in a two-sided hypothesis test involving means or proportions. True False True or false: When the population variance or standard deviation is not know...
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....
The test statistic’s value, the critical value, and the confidence intervals are used to conclude. Below are a few significant hypothesis tests that are employed in inferential statistics.Z Test When data has a normal distribution and a sample size of at least 30, the z test is applied to...

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...
value is for this hypothesis test. We look at the value of the test statistic, and where this is located on a t-distribution with 19 degrees of freedom. For this distribution, we have 4.2 x 10-7as our p-value. (One way to determine this is to use the T.DIST.RT function in ...
In this vein, all traditional methods use equations that estimate the sampling distribution for a specific sample statistic when the data follow a particular distribution. Unfortunately, formulas for all combinations of sample statistics and data distributions do not exist! For example, there is no kn...
The Wald statistic Here is the formula for the test statistic used in the Wald test: where is thesample size, and is a consistent estimate of the asymptotic covariance matrix of (seeCovariance matrix of the MLE). The asymptotic distribution of the test statistic ...
