Step 1
According to the Central Limit Theorem, if the sample size is large enough (usually considered to be over 30), the distribution of the sample mean will be approximately normal, regardless of the shape of the population distribution. Second, the histogram of the Show more…

Find the Probability using the Normal Table using the following formula: z = (X - µ) / σ A population is normally distributed with a mean of µ = 45 and a standard deviation of σ = 4. What is the probability of randomly selecting a score that is greater than 43? In other words, what proportion of the distribution consists of scores greater than 43?

A normally distributed population has mean 57,800 and standard deviation $750 .$ a. Find the probability that a single randomly selected element $X$ of the population is between 57,000 and 58,000 . b. Find the mean and standard deviation of $x-$ for samples of size 100 . c. Find the probability that the mean of a sample of size 100 drawn from this population is between 57,000 and $58,000 .$
