A biologist wants to estimate the difference between the mean body lengths of green and brown stinkbugs is and the standard error is the 0.3411.
What is the standard error?
The general blunders is a statistical time period that measures the accuracy with which a pattern distribution represents a populace via way of means of the usage of general deviation.
Given information a random pattern of 20 greer stinkbugs has an average frame duration of 16.22 millimeters (mm) and a general deviation of 1.34 mm.
- First pattern length n 1 prime =20
- imply of the primary pattern ( X 1 )=16.22mm
- Standard deviation of first pattern (S) = 1.34mm
- First pattern length n2 prime =20
- imply of the primary pattern (x 2 )=13.41mm
- Standard deviation of first pattern (S) = 0.73mm
Standard blunders of the distinction among the pattern method is described via way of means of S.E =0.3411.
