DAsk Tur Teacher Consider a binomial distribution of 200 trials with expected value 80 and standard deviation of about 6.9. Use the criterion that it a unusual to have data values more than 25 standard deviations above the mean or 2.5 standard deviations below the mean to answer the following questions (a) Would it be unusual to have more than 120 successes out of 200 trials? Explain. Yes. 120 is more than 2.5 standard deviations above the expected value. Yes. 120 s more than 2.5 standard deviations below the expected value. No. 120 is less than 2.5 standard deviations above the expected value. No. 120 is less than 2.5 standard deviations below the expected value. (b) Would it be unusual to have fewer than 40 successes out of 200 triais? Explain. O Yes, 40 is more than 2.5 standard deviations above the expected value. Yes. 40 is more than 2.5 standard deviations below the expected value. No. 40 is less than 2.5 standard deviations above the expected value. No. go is less than 2.5 etandard deviations below the expected value. (e) Would it be unusual to have from 70 to 90 successes out of 200 triais? Explain. No. 90 observations is more than 2.S standard deviations above the expected value. No. 70 to 90 observations is within 2.5 standard deviations of the expected value. Yes. 70 to 90 observations is within 2.5 standard deviations of the expected value Yes. 70 observations is more then 25 standard deviations below the expected value DAsk Tur Teacher Consider a binomial distribution of 200 trials with expected value 80 and standard deviation of about 6.9.
