Jacques, an artisan cheese maker, collects data on every step of the cheese-making process for each batch he makes. Jacques noticed that the daily high temperature in his shop on the day he made a batch of cheese was related to the pH of the cheese the next morning. He computed the correlation between the daily high temperature and the pH of the cheese to be −0.64. What information does the correlation provide about the relationship between the daily high temperature and the pH of the cheese?

Daily high temperature and the pH of cheese are inversely related.When one variable increases, the other one decreases.

Step-by-step explanation:

When there is a negative correlation between two variables, it means when one variable increases, the other one decreases.A correlation of -0.64 means that the variable do not have a strong negative correlation because its less that -0.9. However, this correlation is not a weak negative correlation because the value is more that -0.1

Using the concept of correlation coefficients, it is found that the relationship between the daily high temperature and the pH of the cheese is negative and moderate.

---------------------------

Correlation coefficients between two measures assume values between -1 and 1.
If it is negative, the relation is negative(one measure increases as the other decreases), and if it is positive, the relation is positive(both increase together).
If it has an absolute value greater than 0.7, the relation is strong, otherwise is moderate.

---------------------------

In this question, the correlation coefficient between the daily high temperature and the pH of the cheese is of -0.64.
Negative, thus the relation is negative.
Absolute value of 0.64, thus, the relation is moderate.
