Step 1
We are given the population mean (μ) = 1200, the population standard deviation (σ) = 200, and the sample size (n) = 64. We need to find the probability that the sample mean (x̄) is greater than 1200. Show more…

The SAT scores have an average of 1200 with a standard deviation of 60. A sample of 36 scores is selected. a) What is the probability that the sample mean will be larger than 1200? b) What is the probability that the sample mean will be less than 1222? c) What is the probability that the sample mean will be between 1200 and 1214?

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 greater than 1600. b. If 64 SAT scores are randomly selected, find the probability that they have a mean greater than 1600
