The mean score of a college entrance test is 500; the standard deviation is 75. The scores are normally distributed.
May 28, 2019 · The normal distribution is a continuous probability distribution that is symmetrical on both sides of the mean, so the right side of the center is a mirror image of the left side. The area under the normal distribution curve represents probability and the total area under the curve sums to one.
What is the proportion of the total area under the normal curve within plus or minus two (2) standard deviations of the mean? a. 68% b. 99.7% c. 34% d. 95% e. None of above
20) The mean of the sampling distribution of the sample proportion is equal to the population: A) mean B) mean divided by n *C) proportion D) proportion divided by n 21) For sample sizes greater than 30, the sampling distribution of the mean will be approximately normally distributed A) only if the shape of the population is symmetrical.
What proportion of the area under the normal curve falls between a z-score of 1.29 and the mean? Answer: 0.4015 of the area under the curve falls within this range. Note that the table only gives areas corresponding to positive z-scores - i.e., ones falling to the right of the mean.
28.05.2019 · The area under the normal distribution curve represents probability and the total area under the curve sums to one. Most of the continuous data values in a normal distribution tend to cluster around the mean, and the further a value …
A density curve describes the overall pattern of a distribution. The area under the curve and above any range of values on the horizontal axis is the proportion.
Apr 06, 2011 · The area under the normal distribution curve represents the probability of an event occurring that is normally distributed. So, the area under the entire normal distribution curve must be 1 (equal to 100%). For example, if the mean (average) male height is 5'10" then there is a 50% chance that a randomly selected male will have a height that is below or exactly 5'10". This is because the area ...
06.04.2011 · The area under the normal distribution curve represents the probability of an event occurring that is normally distributed. So, the area under the entire normal distribution curve must be 1 (equal to 100%). For example, if the mean (average) male height is 5'10" then there is a 50% chance that a randomly selected male will have a height that is below or exactly 5'10".
State the proportion of a normal distribution within 1 and within 2 standard deviations of the mean; Use the calculator "Calculate Area for a given X" ...
