![]() ![]() The Minitab Calculator is very different from a regular calculator. ![]() Donde la t estadÃstica es 1 y el P-value o la probabilidad es de 0. Tests whether the mean of a single population is equal to a target value. Several types of t-tests exist for different situations, but they all use a test statistic that follows a t-distribution under the null hypothesis: Test. (d) How can you tell that there is insufficient evidence to reject the null hypothesis just by looking at the computer output and not making any additional computations? A t-test is a hypothesis test of the mean of one or two normally distributed populations. ![]() Can the null hypothesis be rejected at the 0.05 level? Why? (b) Is this a one-sided or a two-sided test? (c) Use the output and the t table to find a 99% two-sided CI on the difference in means. (a) Fill in the missing values in the output, including a bound on the P-value. Consider the Minitab output shown on the right. Minitab Statistical Software Has Functionality for Calculating the Power for Many Different Statistical Tests In the following example, an analyst does a power and sample size analysis in Minitab for the 1 proportion test and the 1 sample t test. ![]()
