WebQuestion: Assume that SAT scores are normally distributed with mean μ=1518 and standard deviation σ=325 (based on data from the College Board). a.If 1 SAT score is randomly selected, find the probability that it is between 1550 and 1575. b. If 25 SAT scores are randomly selected, find the probability that they have a mean between 1550 and 1575.
WebHere's how to calculate population standard deviation: Step 1: Calculate the mean of the data—this is \mu μ in the formula. Step 2: Subtract the mean from each data point. These differences are called deviations. Data points below the mean will have negative deviations, and data points above the mean will have positive deviations. WebOct 23, 2024 · The data follows a normal distribution with a mean score (M) of 1150 and a standard deviation (SD) of 150. Following the empirical rule: Around 68% of scores are between 1,000 and 1,300, 1 standard deviation above and below the mean. Around 95% of scores are between 850 and 1,450, 2 standard deviations above and below the mean.
