is FALSE, provide an example that proves your point. If your answer
is true, explain. Given a typical set of numerical data with an ODD
number of values.
1. The mean is always one of the data values.
2. The median is always one of the data values
3. The mode is always one of the data values.
4. The range measures the variability of the given data...

The membrane potential results from charges moving across the
membrane that has a very small effect on the concentrations of the
ions, and as a result there is only a very minor difference in the

IDENTIFY EACH OF THESE STATEMENT AS TRUE OR FALSE. If the
statement is true ,explain why .if it is false ,give a
counterexample.(a) if the diagonals of a quatrilateral are
congruent,but only one is the perpendicular of the other,then the
quadrilateral is a kite. (b) if the quadrilateral has exactly one
of reflectional symmetry,then the quadrilateral is a kite. (c) if
the diagonals of a quadrilateral are congruent and bisect each
other,then it is square

believe that the statement is false, briefly explain why you think
it is false.
Small p-values of the chi-squared test of independence
indicate that the data have small amounts of dependence.
(a) The statement is true
(b) The statement is false because when the p-value of the
chi-squared test of independence is small, the results indicate
that the two variables are more dependent.
(c) The statement is false because...

false or rewrite the statement so that it is true.
If a scatterplot shows a linear association
between two numerical variables, then a correlation coefficient
that is close to 1 indicates a strong positive trend and a
correlation coefficient that is close to 0 indicates a strong
negative trend.
