If the mean of a data set is 92 and standard deviation is 20, what is the typical range of values?
13. Below are the range and standard deviation for a set of
data. Use the range rule of thumb and compare it to the standard
deviation listed below. Does the range rule of thumb produce an
acceptable approximation? Suppose a researcher deems the
approximation as acceptable if it has an error less than 15%.
The estimated standard deviation is
Is this an acceptableapproximation?
A:.No, because the error of the range rule of thumb's
approximation is
greater than 15%.
B.Yes, because...

Assume that a normal distribution of data has a mean of 20 and a standard deviation of 5. Use 68 - 95 - 99.7 rule to find the percentage of values that lie above 15. What is the percentage of values lie above 15?
The brain volumes (cm3) of 20 brains have a mean of 1118.2 cm3 and a standard deviation of 129.3 cm3 . Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1326.8 cm3 be significantly high? Significantly low values are ____ cm3 or lower. Significantly high values are ____ cm3 or higher.
The standard deviation for a set of temperatures is 7.6 and the mean is 53.6. The data is left skewed. Use Chebyshev’s Theorem to find what the range of values are that will make up at least 75% of the data. That is what is the range of values that are 2 standard deviations from the mean?

#4 (4a) You have a data set with a mean of 50 and a standard deviation of 10. If you add 3 to every data point, what will be the new values for the mean and standard deviation. Briefly explain your answer. (4b) The standardized score for the minimum of a data set is Zmin median is zmed = -0.6, and the standardized score the maximum of the data set is zmin +6.8. Based on this information alone, describe the...
