Example With R use built-in math and statistics functions find the P-value for a left tailed hypothesis test for a mean. Here, the sample size is 30, the sample mean is 62.1, the sample standard deviation is 13.46, and the test is for a mean smaller 60. # Specify the sample mean ...
All that formula is saying is add up all of the numbers in your data set ( Σ means “add up” and ximeans “all the numbers in the data set). This article tells you how to find the sample mean by hand (this is also one of theAP Statistics formulas). However, if you’re findi...
