2a) 5000 kindergarteners took a reading test and the scores were distributed normally with an average of a 70 and a standard deviation of 5 points. Label the mean and 3 standard deviations above and below the mean on the image of a normal curve below. 2b) Recall that z-scores put scores in terms of standard deviations away from the mean. If one kindergartener receives a z-score of z = 1.75, what was their score on the test? 2c) If a child receives a z-score of z = -1.5, what was their score on the test
