8. 5 point
A simulation was run 200 times using a
population with a proportion of 0.35 and a
simulated sample size of 50. The simulated
sample proportions are shown below. Based on
this distribution, what is the probability of
obtaining a sample of 50 with a sample proportion
greater than 0.45?

Ur environment is very sensitive to the amount of ozone in the upper atmosphere. the level of ozone normally found is 4.04.0 parts/million (ppm). a researcher believes that the current ozone level is not at a normal level. the mean of 2525 samples is 4.44.4 ppm with a standard deviation of 0.80.8. assume the population is normally distributed. a level of significance of 0.020.02 will be used. make the decision to reject or fail to reject the null hypothesis. answer tables
