NettetStudy with Quizlet and memorize flashcards containing terms like T/F The sample standard deviation is calculated by taking the square root of the population standard deviation, T/F An advantage of the median instead of using mean as the measure of central tendency is that it is not affected by extremely large or extremely small values in the data set, A … NettetExpert Answer. A random sample of 25 values is drawn from a mound-shaped and symmetric distribution. The sample mean is 8 and the sample standard deviation is 2. Use a level of significance of 0.05 to conduct a two-tailed test of the claim that the population mean is 7.5.
