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.

Answer with Explanation:
The <em>peak, trough, recession and recovery</em> are stages of the "Business Cycle." They can be represented in a line graph as points that represent individual stages. Each can tell what a country's economy is experiencing in terms of fluctuations happening in economic activities.
The peak is that highest point in the graph. It means that the economy is producing the maximum output that it is allowed to do so.
The trough is the lowest point in the graph. This marks the<em> end of depression.</em> This means that soon, the<em> economy will try to recover.</em>
The recession is that point on the graph that goes down following the peak. This is a period of economic decline or contraction. Here, the production decreases.
The recovery is that point on the graph that goes up following the trough. This stage is marked by increase in demand and production. It is considered to be the end of the business cycle.
