Answer :

Final answer:

The best predicted weight for an adult male who is 154 cm tall is approximately -95.91 kg.

Explanation:

To find the best predicted value of weight given an adult male who is 154 cm tall, we can use the regression equation:

Weight = Slope * Height + Intercept

From the given information, we have:

  • Correlation coefficient (r) = 0.81389
  • Slope (b) = 0.0402
  • Intercept (a) = -102.111
  • Height (x) = 154 cm

Substituting these values into the regression equation:

Weight = 0.0402 * 154 - 102.111

Simplifying the equation:

Weight = 6.2008 - 102.111

Weight = -95.9102 kg

Therefore, the best predicted weight for an adult male who is 154 cm tall is approximately -95.91 kg.
