Biologists studying horseshoe crabs want to estimate the percent of crabs in a certain area that are longer than 35 centimeters. The biologists will select a random sample of crabs to measure.

Which of the following is the most appropriate method to use for such an estimate?

I need the answer and the explanation, please.

The most appropriate method to use for the estimate of population of crabs longer   than 35 cm

1 A one sample z interval for the population proportion

Hence option (1) is correct.

Biologists studying horseshoe crabs want to estimate the percent of crabs in a certain area that are longer than 35 centimeters.

The biologists will select a random sample of crabs to measure

we have to determine that  of the following is the most appropriate method to use for such an estimate

1. A one sample z interval for the population proportion

2. A one sample z interval for the sample proportion

3. A two sample z interval for the population  proportion

4. A two sample z interval for a difference between population proportion

5. A two sample z interval for a difference between sample proportion

Z interval is a type of confidence interval which tells us about  

a range where we can expect a particular mean or proportion to fall.  

It can be calculated from a known standard deviation.

A confidence interval is a range of plausible values in which the true population parameter  is believed to lie.

Hence option (1) is correct.

A.one sample z-confidence interval for the population proportion

Step-by-step explanation:

-A confidence interval is a range of values in which the true population mean is believed to lie.

-Given just one sample, the one sample z-confidence interval for the population proportion is appropriate and is defined as:
