Explanation of Solution
Correlation is measure of linear association between two variables. The variables are said to be correlated when the change in one variable affects the other variable.
The
If two variables have a very strong positive relation, then the correlation value lies between .8 and 1. If two variables have a strong correlation, then correlation falls between .6 and .8. If two variables have a moderate positive relation, then the correlation value lies between .4 and .6. If two variables have a weak positive relation, then the correlation value lies between .2 and .4. And, if two variables have a very weak positive relation, then the correlation value lies between .0 and .2.
Similarly, if two variables have a very strong negative relation, then the correlation value lies between

A population that is uniformly distributed between a=0and b=10 is given in sample sizes
50( ),
100( ),
250( ),
and
500( ).
Find the sample mean and the sample standard deviations for the given data. Compare your results to the average of means for a sample of size 10, and use the empirical rules to analyze the sampling error. For each sample, also find the standard error of the mean using formula given below.
Standard Error of the
Mean =sigma/Root

Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with large adjusted gross incomes. If a taxpayer claims larger than average itemized deductions for a given level of income, the chances of an IRS audit are increased.
