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:

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
