It is generally believed that only 7% of the population has type O-negative blood (the universal donor). A blood bank is expecting 1000 donors at its upcoming drive. In our drive of 1000 donors, we found 8.5% of the donors were O-negative. Construct a 90% confidence interval for the number of O-negative donors we would expect to see based on our sample. Does this support or refute the estimate of 7%? Assume conditions are met (so don't check them)! Conditions:...
