SpyIntel [72]

Answer:

The correlation between hour of the day and the speed over the limit at which the motorist is ticketed is weak positive correlation.

Step-by-step explanation:

The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.

The types of correlation coefficient are:

  • +1 (-1) : Perfect positive (negative) correlation
  • 0 to 0.30(-0.30) : Weak positive (negative) correlation
  • 0.30(-0.30) to 0.70(-0.70) : Moderate positive (negative) correlation
  • 0.70(-0.70) to 1 (-1) :  Strong positive (negative) correlation

The correlation coefficient value between the hour of the day and the speed over the limit at which the motorist is ticketed is:

<em>r</em> = 0.12.

The value of <em>r</em> lies between:

0 < 0.12 < 0.30

Thus, the correlation between hour of the day and the speed over the limit at which the motorist is ticketed is weak positive correlation.
