Question

question 7 (1 point)
a correlation of ( r = + 0.10 ) suggests
a a strong positive relationship
b a strong negative relationship
c no relationship
d a weak positive relationship

question 8 (1 point)
if the mean is higher than the median, the distribution is most likely
a negatively skewed with a very low outlier
b normal
c positively skewed with a very high outlier
d bimodal

Explanation:

Question 7

The correlation coefficient \( r \) ranges from - 1 to + 1. A positive \( r \) value indicates a positive relationship. The closer \( r \) is to 1 (or - 1), the stronger the relationship. Since \( r = + 0.10 \) is close to 0, it is a weak positive relationship.

In a positively skewed distribution, the tail is on the right - hand side. A very high outlier (in the right - hand tail) will pull the mean towards it. The median is less affected by outliers. So, when the mean is higher than the median, the distribution is most likely positively skewed with a very high outlier.

Answer:

d. A weak positive relationship
