Question 1175850: This is a statistics homework question, I'm a bit lost on how to go about it. I would greatly appreciate the help:
In 2014, 6% of the cars sold had a manual transmission. A random sample of college students who owned cars revealed the following: out of 122 cars, 26 had manual transmissions. Estimate the proportion of college students who drive cars with manual transmissions with 90% confidence.

Hi

Sample mean = 26/122 = .213



ME = 



Me =  = ±  .061



.213 - .061<  < .213 + .061

     .152 <  < .274
