To calculate the standard error, you need to divide the standard deviation by the square root of the sample size.

Standard Error = Standard Deviation / √(Sample Size)
Standard Error = 3.5 / √(5)
Standard Error = 3.5 / √5
Standard Error ≈ 3.5 / 2.24
Standard Error ≈ 1.56

Therefore, the standard error is approximately 1.56 when rounded to the nearest hundredth.

can you rounded to the nearest hundredth what would be the answer

The rounded answer to the nearest hundredth would be 1.56.
