All Ages:- 9, 13, 9, 10, 10, 9, 10, 10, 11, 9

No. of ages = 10

\therefore Mean = \frac{9 + 13 + 9 + 10 + 10 + 9 + 10 + 10 + 11 + 9}{10}  \\  \\  =  \frac{100}{10}  \\  \\  = \bold{10}

A Pearson correlation (symbolized by the letter r) is normally used to summarize the association, or correlation, between two va
avanturin [10]

Answer:

False

Step-by-step explanation:

We are given the following in the question:

Pearson correlation = 1.30

Pearson coefficient:

  • The range of Pearson coefficient is from [-1,1]
  • A positive correlation means that an increase in one quantity leads to an increase in another quantity
  • A negative correlation means with increase in one quantity the other quantity decreases.
  • +1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.

Since, the given coefficient of Pearson does not lies in the range, it cannot express relation between two quantities.

Thus, a value of 1.30 does not indicates a strong correlation.

Thus, the given statement is false.
