... 32) For a given level of significance, increasing the sample size will always decrease the probability of committing a Type I error. 33) The actual P-value is less informative than reporting the result of the test as “Reject Ho” versus “Do Not Reject Ho”. 34) If the P-value of the test statistic was ...

... 78. (C) The interquartile range (lQR) is obtained by subtracting Qr from p:, therefore IQR= (49 - 27) = 22. To determine the existence of an outlier, compute 1.5 x IQR add this value to Q: and subtract it from Qt lf any piece of data falls outside the range of these two values, it is an outlier. ...

Confidence intervals for the mean of one population
... Population: the totality of items or individuals under consideration. A population can be finite (can be counted) or infinite (can not be counted). Sample : portion of the population that is selected for the analysis. A sample is characterized by its size n, which refers to the number of observation ...
