This value of 41.7±3.6% represents a range of values rather than a single value, and is typically used to represent the standard error of a sample mean. The standard error is a measure of the variability of sample means around the true population mean, and is calculated by dividing the standard deviation of the sample by the square root of the sample size.
In this case, the ±3.6% represents the margin of error around the sample mean of 41.7%. This means that we are 95% confident that the true population mean falls within the range of 38.1% to 45.3%. It is used to estimate the uncertainty in the sample mean and is commonly used in hypothesis testing and confidence interval calculations.
41.7±3.6%, is this standard error or standard deviation explain why
