How is the p value of a hypothesis determined?
The P -value approach involves determining "likely" or "unlikely" by determining the probability — assuming the null hypothesis were true — of observing a more extreme test statistic in the direction of the alternative hypothesis than the one observed. If the P -value is small, say less than (or equal to) α, then it is "unlikely."
What should the confidence interval be in StatCrunch?
For this example, in the window containing the hypothesis test results above, choose Options > Edit to reopen the dialog window. Under Perform, choose Confidence interval for μ. By default StatCrunch has a value of 0.95 for the Level input which will produce a 95% confidence level for the population mean, μ.
