- Modified True or False VIFs exceeding 10 are sign of low autocorrelation.Suppose that the probability that any stock increases in price (over a 3 month period of time) is 60%. What is the probability that in a sample of 115 stocks that you buy that less than 65% increase in price (over a 3 month period of time)? (please round your answer to 4 decimal places) Please explain using ti89 or Excell functions.The National Vaccine Information Center estimates that 90% ofAmericans have had chickenpox by the time they reach adulthood. We now consider a random sampleof 120 American adults. We want to find out the probability that 110 or more people in this samplehave had chickenpox in their childhood use normal approximation to approximate the probability that 110 or more people in this samplehave had chickenpox in their childhood. Do not use continuity correction.
- please use sturge's formula to calculate class intervalAn accounting professor claims that no more than one quarter of undergraduate business students will major in accounting. What is the probability that in a random sample of 720 undergraduate business students, 170 or more will major in accounting? Use technology to find the probability, using 3 decimal places in your z-score. Give your answer to at least 4 decimal places. Don't forget the continuity correctionUse Simpson’s Rule with n = 4 intervals to approximate
