At a certain college, it is estimated that at most 33% of the students ride bicycles toclass. Does this seem to be a valid estimate if, in a random sample of 81college students, 34 are found to ride bicycles to class? Use a 0.10 level of significance.Click here to view page 1 of the standard normal distribution table.Click here to view page 2 of the standard normal distribution table.Let a success be a student that rides a bicycle to class.
