distributions, since µ and ? determine the shape of the distribution About 2/3 of all cases fall within one standard deviation of the mean, that is

A r v with this distribution is called a standard normal formula • These probabilities can then be found “normal tables” deviation ?, then

Or, in terms of the formula, A z table can be used to calculate that 9938 of the scores are less than or equal to a score 2 5 standard deviations above

and its standard deviation is 1 893 / sqrt(25) = 0 379 ?That calculation gives us the standard error of the mean, i e , the estimated standard deviation of

Given the mean and standard deviation of a normal curve, we'd like to approximate the The standardized value for x, calculated by the formula above,

3 1 Finding areas under the standard normal curve The standard normal distribution has a mean of 0 and a standard deviation and variance

the mean and the variance do not completely determine the distribution, by a normal distribution with a mean of 3 and a standard deviation of 4

Find the 0 6 quantile of the standard normal distribution answer: We don't have a formula for the cdf, so we use the R 'quantile function' qnorm q0

TI Calculator Steps: Caluclating area under the standard normal curve then you will have normalcdf(lower bound, upper bound, mean, standard deviation)
