In one of Sue's experiments, 500 plants were treated with a chemical and 350 of them were found to have a plant disease. Use a 0.01 significance level to test the claim that the rate of plant disease among all plants treated with the chemical is equal to 74%.

State the final conclusion.

Applicable answers:

  1. The sample evidence does NOT support the rejection of the null hypothesis claim that the rate of plant disease among all plants treated with the chemical is equal to 74%
  2. The sample evidence does support the rejection of the null hypothesis claim that the rate of plant disease among all plants treated with the chemical is equal to 74%
  3. The sample evidence does NOT support the rejection of the Sue's claim that the rate of plant disease among all plants treated with the chemical is equal to 74%
  4. The sample evidence does support the rejection of the Sue's claim that the rate of plant disease among all plants treated with the chemical is equal to 74%
