"While bird watching, Carl hypothesized he could identify 73 different types of birds in one day. He actually identified 65 different types of birds. What was his percent error

15.87%

Explanation:

Carl's percentage error would be 15.87%.

From the data, the hypothesized number of birds Carl could identify is 73.

The actual number of birds he was able to identify is 63.

The margin of error between the two = 73 - 63 = 10.

Hence, percentage error = error/true measurement x 100%

               = 10/63 x 100% = 15.87%

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction
