Degrees of freedom is calculated by

• dividing the standard deviation by the square root of the sample size

• subtracting one from the sample size

• adding together all values and dividing by the sample size

• squaring the difference between the observed and expected values

Students in a biology class planted five tomato seeds in separate containers. They exposed the seeds to an artificial light source for 20 days. At the end, they measured the height of the plant. The data is shown in the table. What is the mean of the data?

• 55

• 61

• 72

• 103
