Suppose that the true proportion of drivers who never wear a seat belt is 23% In a random sample of n = 200 drivers, 50 individuals say they never wear a seat belt when driving.
Give a numerical value for p-hat.
Calculate the standard deviation for the sampling distribution of p-hat. Give answer to 4 decimals.
In a different survey of 400 people, 100 people say they never wear a seat belt. Calculate p-hat.
For the survey of 400 people, calculate the standard deviation for p-hat. Give answer to 4 decimals.
please explain...i do not need answers
