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.
'Horse Drawn Vehicles' were once the primary transportation method, and there were 3 involved animals, horses, mules, and oxen, although horses were the original go to for a carriage, due to fast movement, oxen soon became popular amoungst emigrants.
Answer: On the Northern horizon
Explanation:
If the star is directly overhead when you stand at the North Pole, it will sink further and further the more you move south towards the equator due to the earth's curve. When you get to the equator, the star will ideally sit right on the northern horizon.
After one crosses the equator however, the star will disappear from view. It is therefore not possible to see this star from anywhere south of the Equator to the South Pole.
