Answer: There is a weak, positive correlation between the weight Lucy lost and the number of weeks.
Explanation:
The correlation coefficient is used to measure the relationship between two variables in terms of how they move in relation to one another.
If two variables are said to have a positive correlation, it means that they increase at the same time and decrease at the same time for example, there is a positive correlation between the amount of food a family buys and how much money they have because the more money they have, the more food they buy.
Negative correlations are the reverse for instance Ice cream sales and cold temperatures. The colder it is, the less people buy ice cream.
The Correlation coefficient ranges from -1 to +1 with +1 (-1) meaning that the variables are perfectly positively(negatively) correlated. The closer the value is to 0, the weaker the correlation.
Generally, for a correlation coefficient between the numbers 0 and +0.3, there is a weak positive correlation.
With a correlation coefficient of 0.0502, there is therefore a weak, positive correlation between the weight Lucy lost and the number of weeks.
Friedman and Johnson (1997) show that for a wide range of dynamic optimization problems, supermodularity is both necessary and sufficient for monotone static results. In the present context, this implies that our supermodular model requires the minimum set of assumptions to obtain monotonicity in the optimal decision variables.

The evidence presented here needs to be supplemented with information about inter- and intrafamily income transfers. This issue was addressed in a follow-up survey, but analysis of the results is not yet complete.
D) selecting random sample allows for a more representative sample in a survey.
Answer: what the heck of questions is this
Explanation:
Answer:
The trees rustled as the wind whistled gently through the leaves- The noises are considered imagery.
Her mouth watered and her tongue burned as she bit into the spicy sandwich.- Considered taste imagery because it is describing what the girl is doing.
The golden rays of the setting sun reflected upon the clear waters of the lake. - Visual imagery
My toes went numb and a shiver ran up my spine as I stepped into the cold water.
The stench of rotting garbage overpowered me when I opened the bin.
Hope these are correct :)
