Answer

Explanation:

Step1: Recall the concept

The best estimate of the population mean from sample means is the mean of the sample means.

Step2: Calculate the sum of sample means

$154 + 121+160 + 135+140+134+129=973$

Step3: Calculate the number of samples

There are 7 samples.

Step4: Calculate the mean of sample means

$\frac{973}{7}=139$ However, among the given options, we choose the value closest to 139.

Answer:

136
