A random sample of 47 University sophomores was taken who use any kind of visual aids.It was found that 34 of them uses contact lens.
a. What is the estimate of the proportion of students who use contact lense?
Isn't this just 34/47? Which would be .7234?
b. Calculate the standard error of your estimate.
No idea how to do that.
Help please?
Thank you!
