Yes
False. It can be skewed to the left or right or be symmetrical.
False. When the range is large you would use a grouped frequency distribution.
The statement is false. The binomial distribution (discrete) or uniform distribution (discrete or continuous) are symmetrical but they are not normal. There are others.
False. For example; your name is ___________.
false
False. It can be skewed to the left or right or be symmetrical.
The F-distribution is either zero or positive, so there are no negative values for F. This feature of the F-distribution is similar to the chi-square distribution. The F-distribution is skewed to the right. Thus this probability distribution is nonsymmetrical.
True
This is true
In a negatively skewed distribution, the mean is typically less than the median, and the median is less than the mode. This results in a tail that extends longer to the left. Therefore, any statement claiming that the mean is greater than the median or that the mode is less than the median would be false. Thus, one must be careful to identify which statements accurately reflect the characteristics of negatively skewed distributions.
False. A proton is positively charged and found in the nucleus of an atom, not in the orbitals where electrons are located.
The statement is true that a sampling distribution is a probability distribution for a statistic.
False. When the range is large you would use a grouped frequency distribution.
false
Generally false. In a parallelogram, the opposite angles are equal. They could be complementary in a highly skewed parallelogram in which one angle is 45 degrees.
False. When an atom gains electrons, it becomes negatively charged, not positively charged. This is because electrons are negatively charged particles.
The statement is false. The binomial distribution (discrete) or uniform distribution (discrete or continuous) are symmetrical but they are not normal. There are others.
