Many people can roll their tongues, but some can't. Javier is interested in determining the proportion of
students at his school that can roll their tongue. In a random sample of 100 students, Javier determines
that 70 can roll their tongue. The dotplot below shows the proportion of people who can roll their tongue in
each of 500 random samples of size 100 from a population where 70% can roll their tongue.

at his school that can roll their tongue.
2. Interpret the margin of error.

Expert Solution

Step 1

Here we have to calculate margin of error

Assuming the confidence Interval = 95%

Sample Size = 500

Mean Value = 0.701

Standard deviation = 0.048
