Reference no: EM131793069

Hand Washing Ignaz Semmelweiss (1818-1865) was the doctor who first encouraged other doctors to wash their hands with disinfectant before touching patients.

Before the new procedure was established, the rate of infection at Dr. Semmelweiss's hospital was about 10%. Afterwards the rate dropped to about 1%.

Assuming the population proportion of infections was 10%, find the probability that the sample proportion will be 1% or less, assuming a sample size of 200.

Start by checking the conditions required for the Central Limit Theorem to apply.
