Question 43

An estate agent believes there is a positive correlation between the size of a house's garden and its selling price.

She calculates the product moment correlation coefficient for a random sample of 25 houses and obtains r=0.352r = 0.352r=0.352.

Carry out a suitable test to investigate the estate agent's belief at a 5% level of significance.

State clearly

  • your hypotheses
