The TI-83 Plus family of graphing calculators calculates two types of standard deviation: the standard deviation of the sample and the population standard deviation. The population standard deviation, denoted by s x, divides the calculated values by n. The sample standard deviation, denoted by Sx, uses the value n-1 as the denominator.

Standard deviation can be calculated using several methods on the TI-89 family, TI-92 family and Voyage 200 graphing calculators. Standard deviation can be calculated by using the stdDev() function.

A t-test is used here since we have a big enough sample, and the population standard deviation is unknown. (We only have the standard deviation from the sample: .) Note that if we knew the population standard deviation, we would use a z-test instead. 1.Step 3: Interpret the results. Our calculator will automatically produce the results of the one-sample t-test: μ≠20: This is the alternative hypothesis for the test. t=1.919896124: This is the t test-statistic. p=0.0587785895: This is the p-value that corresponds to the test-statistic. x=21.59.

To answer this, we must find the z-score that is closest to the value 0.15 in the z table. This value turns out to be -1.04: We can then plug this value into the percentile formula: Percentile Value = μ + zσ. 15th percentile = 60 + (-1.04)*12. 15th percentile = 47.52. An otter at the 15th percentile weighs about 47.52 pounds.
