Question

An agricultural researcher is interested in estimating the mean length of the growing season in a region. Treating the last 10 years as a simple random​ sample, he obtains the following​ data, which represent the number of days of the growing season. What is the point estimate of the population mean number of days of the growing​ season? 151 164 146 143 167 188 190 180 170 148 The point estimate is nothing.

Answer 1

The point estimate of the population mean is 164.7

Explanation:

Given

`n =10`

`Data: 151\ 164\ 146\ 143\ 167\ 188\ 190\ 180\ 170\ 148`

Required

The point estimate of the mean

To do this, we simply calculate the sample mean using;

`\bar x =(\sum x)/(n)`

`\bar x =(151 +164 +146 +143 +167 +188 +190 +180+170 +148)/(10)`

`\bar x =(1647)/(10)`

`\bar x =164.7`
