Otrada [13]

Answer:

See Explanation

Explanation:

The question is incomplete as the diameters of the Willapa Bay urchins were not given.

However, I'll give a general way to solve this problem.

Average is calculated using:

Average = \frac{\sum x}{n}

i.e. Sum of all diameters divided by the number of bay urchins.

The diameter of urchins is usually between 6cm to 12cm; So, I will assume the following diameters for 10 urchins.

10cm, 8cm, 10cm, 7cm, 9cm, 10cm, 6cm, 10cm,8cm, 8cm

Using the above data, the average is:

Average= \frac{10+8+10+7+9+10+6+10+8+8}{10}

Average= \frac{86}{10}

Average= 8.6
