A random sample of 225 full time students at a large two-year college is taken to estimate the amount they spent on text books this semester. The sampled students spent an average of $200 with a standard deviation of $75. Thus, a 95% confidence interval for the average amount spent by all full time students at that school would be: Group of answer choices $200 ± $0.33 $200 ± $5 $200 ± $10 $200 ± $75
