sample sample mean 1 154 2 121 3 160 4 135 5 140 6 134 7 129 looking at this table of sample means, which value is the best estimate of the mean of the population? 120 136 160 168

Answer

Explanation:

Step1: Calculate sum of sample means

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

Step2: Calculate number of samples

There are 7 samples.

Step3: Calculate the mean of sample means

$\frac{973}{7}=139$ The value closest to 139 among the options is 136.

Answer:

136
