The SAT test has a mean of 1200 with a standard deviation of 60 A sample of 36 scores is selected What is the probability that the sample mean will be between 1200 and 1214?
To find the probability that the sample mean is between 1200 and 1214, we can use the Central Limit Theorem. The standard error (SE) of the sample mean can be calculated as SE = standard deviation / √n = 60 / √36 = 10. We then standardize the sample means using the z-score formula: ( z = (X - \mu) / SE ). For 1200, ( z = (1200 - 1200) / 10 = 0 ), and for 1214, ( z = (1214 - 1200) / 10 = 1.4 ). Using standard normal distribution tables, the probability of the z-score being between 0 and 1.4 is approximately 0.4192, or 41.92%.
