In a recent survey of 150 teenagers, 93 stated that they always wear their seatbelt when they travel in a car. Assuming the distribution is approximately normal, find the point estimate and standard error for the proportion of teenagers that always wear a seatbelt when traveling in a car. Round your answers to three decimal places, as needed.

The estimated standard error is given by:

Step-by-step explanation:

For this case we have the following data:

n =150 represent the sample size selected

x = 93 people stated that they always wear their seatbelt when they travel in a car

For this case the the proportion estimated is :

We can can check if we can use the normal approximation :

So then we can use the normal approximation and the distribution for the proportion is given:

The estimated standard error is given by:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
