In the first table, y = 4x. So y is proportional to x.

In the second table, y is not proportional to x.

In the third table, 2y = 3x. So, y is proportional to x.

Answer:

The standard deviation of the sampling distribution of sample means would be 0.8186.

Step-by-step explanation:

We are given that

Mean of population=23.2 pounds

Standard deviation of population=6.6 pounds

n=65

We have to find the standard deviation of the sampling distribution of sample means.

We know that standard deviation of the sampling distribution of sample means

= $\frac{\sigma}{\sqrt{n}}$

Using the formula

The standard deviation of the sampling distribution of sample means

= $\frac{6.6}{\sqrt{65}}$

$=0.8186$

Hence, the standard deviation of the sampling distribution of sample means would be 0.8186.
