Level of significance

At a certain college it is estimated that 25% of the students have cars on campus. Does this seem to be a valid estimate if in random sample of 90 college students, 28 are found to have cars? Use a 0.05 level of significance.



Step-by-step explanation:

q=25%=25100=0.25 n=90 n1=28 α=0.05 x=1=1
