12. 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___
(Round to three decimal places as needed.)
s this an acceptableapproximation?
A:.No, because the error of the range rule of thumb's approximation is
greater than 15%.
B.Yes, because the error of the range rule of thumb's approximation is
less than 15%.
C. Yes, because the error of the range rule of thumb's approximation is
greater than 15%.
D:.No, because the error of the range rule of thumb's approximation is
less than 15%.
Using range rule of thumb std deviation =range/4=2.83/4= 0.7075
Error=0.872-0.708/0.708*100
= 0.164/0.708*100
=0.01242887*100
=1.242887
<15%
ANSWERS
the estimated standard deviation is 0.708
B.Yes, because the error of the range rule of thumb's approximation is
less than 15%.

a researcher has a data set with a mean score of 45 and standard deviation of 15 . Assuming that the data set is normally distributed, the researcher would expect approximately 95% of the data to fall between a 35 and 55 b 30 and 60 c 40 and 50 my answer is c can some one draw the bell curve and show me step by step how this is done . thanks
