![]() X ~ N(63, 5), where mean, μ = 63 and standard deviation,σ = 5. Find the probability that a randomly selected student scored more than 65 on the exam.Let X = a score on the final exam. ![]() Find the 70th percentile (that is, find the score k such that 70% of scores are below k and 30% of the scores are above k).Find the 90th percentile (that is, find the score k that has 90% of the scores below k and 10% of the scores above k).Find the probability that a randomly selected student scored less than 85.Find the probability that a randomly selected student scored more than 65 on the exam.The final exam scores in a statistics class were normally distributed with a mean of 63 and a standard deviation of 5.
