8.1.7 point estimated

A simple random sample is taken from a population and yields the following data for a variable of the population.

Find a point estimate for the population mean​ (that is, the mean of the​ variable).

First, we need to get the data from Excel. (The approach below gets the data mannually)

data <- c(11, 23, 38, 13, 35, 16, 36, 19, 16, 27)

---

To find point estimated, we run

mean(data)

## [1] 23.4

Round to one decimal place as needed

round(mean(data), 1)

## [1] 23.4

Hope that helps!
