**Impact of Sample Size on Accuracy**Compute the standard error for sample means from a population with mean $ \mu = 80 $ and standard deviation $ \sigma = 25 $ for sample sizes of $ n = 35 $, $ n = 230 $, and $ n = 1000 $.Round your answers to two decimal places.| Sample Size | Standard Error ||-------------|----------------|| $ n = 35 $ | [Input Field] || $ n = 230 $ | [Input Field] || $ n = 1000 $ | [Input Field] |In this exercise, you'll calculate how the standard error changes as the sample size increases. Use the formula for standard error: \[ SE = \frac{\sigma}{\sqrt{n}} \]Where:- $ SE $ is the standard error- $ \sigma $ is the standard deviation- $ n $ is the sample sizeThis will demonstrate the impact of different sample sizes on the accuracy of sample means.
