Students' performance scores in a statistic test have a mean of 70 and a standard deviation of 4.0
The scores obtained can be modeled by a normal distribution
Find the probability that the score of a randomly selected student is i More than 80 marks ii. For positive infinity enter 1e99 Then, enter the mean and standard deviation
The scores on the exam have an approximate normal distribution with a mean μ = 81 points and standard deviation σ = 15 points This calculator finds mean, standard deviation and variance of a distribution
