Document Summary
Z distribution: 100 fly, 70 land on soft surface. The binomial distribution, when the number of trials is large and pron of success p is not close to 0 or 1, is approx. by a normal distribution having mean np and standard dev. Step 2: define the terms going into the equation. For 100, the z value is greater than for 50. The 100 fly experiment, the observation is more stand. The prob of the z value for 100 flies is 0. 00003 (table b). The probability of the z value for 50 flies is 0. 002. To get the 2-tailed probability, we must multiply both by: the prob of getting the result in the 100 fly experiment is much lower than in the. For y to be > %10 from the mean y*u= 4000*0. 1=400. Z-distribution assumptions: the original distribution is normally distributed with know parameters.
