How to solve a normal distribution problem
WebThe pnorm function. The pnorm function gives the Cumulative Distribution Function (CDF) of the Normal distribution in R, which is the probability that the variable X takes a value lower or equal to x.. The syntax of the function is the following: pnorm(q, mean = 0, sd = 1, lower.tail = TRUE, # If TRUE, probabilities are P(X <= x), or P(X > x) otherwise log.p = … Once you have the mean and standard deviation of a normal distribution, you can fit a normal curve to your data using a probability density function. In a probability density function, the area under the curve tells you probability. The normal distribution is a probability distribution, so the total area under the curve is … See more All kinds of variables in natural and social sciences are normally or approximately normally distributed.
