Answer:

164.3

Step-by-step explanation:

Point estimate can be found by finding the mean of the sampling data. In this case agricultural researcher samples last 10 years as a simple random​ sample and obtains the following data:

150 157 145 141 173 193 187 179 171 147

The mean of the data can be calculated by simply adding them and dividing by 10:

[tex]\frac{(150+157+145+141+173+193+187+179+171+147)}{10} =164.3[/tex]
