WebbQuestion: In a normal distribution, what is the probability that a random sample of 453 with population proportion 0.24 has a sample proportion of less than 0.21? Level of difficulty … Webb3 jan. 2024 · Normal Distribution Definition. A continuous random variable X is said have normal distribution with parameter μ and σ if its probability density function of normal distribution is given by : { 1/ [ σ * sqrt (2π) ] } * e- (x - μ)2/2σ2. Where, X = random variable. μ = mean. σ = standard deviation. π = 3.14159.

WebbA population of values has a normal distribution with μ=190.9 =190.9 and σ=52.8 =52.8. You intend to draw a random sample of size n=172 =172. Find the probability that a single randomly selected value is between 201.4 and 203. Find the probability that a sample of size n=172 =172 is randomly selected with a mean between 201.4 and 203. Webb29 jan. 2024 · However, the normal distribution is a continuous probability distribution while the binomial distribution is a discrete probability distribution, so we must apply a continuity correction when calculating probabilities. In simple terms, a continuity correction is the name given to adding or subtracting 0.5 to a discrete x-value. division formula in word table
