9 godz. temu · Step 4/6 Compute the sample mean (which is the point estimate for the population mean) using the formula: \[ \bar{x} = \frac{1}{n} \sum_{i=1}^{n} x_i \] Step 5/6 Substitute the values from the sample data into the formula to find the sample mean. Answer The result from Step 5 is the point estimate for the population mean. Let's think step by step.
