Question

The table shows the data of a random sample of fish that were collected from and later released into a lake.

Type of Fish Bass Eel Gar
Number of Fish 92 56 52


How many gars are estimated to be present if a random sample of 1,000 fish is collected from the lake?
104
108
260
320

Answer 1

there was a total of 200 fish collected and released from the pond...of those, 52 were gar......52/200 = 0.26 = 26%

so if 1000 fish are collected....26% of 1000 = 0.26(1000) = 260 gar <==

Answer 2

Gars estimated to be present if a random sample of 1,000 fish is collected from the lake are:

260

Explanation:

According to the given sample there was a total of 200(92+56+52) fish collected from a lake.

Of those, 52 were gar.

52/200 = 0.26 = 26%

i.e. 26% of the total fishes collected were jar

So, if 1000 fish are collected

26% of 1000 =
`(26)/(100)* 1000`

= 260

i.e. 260 fishes were jar

Hence, gars estimated to be present if a random sample of 1,000 fish is collected from the lake are:

260
