Given a standard error of 7.8 and a sample size of 10, what is the standard deviation? Round to the nearest hundredth.
To calculate the standard deviation, we need to multiply the standard error by the square root of the sample size.
Standard deviation = standard error * sqrt(sample size)
Standard deviation = 7.8 * sqrt(10)
Standard deviation = 7.8 * 3.1623
Standard deviation = 24.63554
Rounded to the nearest hundredth, the standard deviation is 24.64.
