Question: Health status of UNCC students was investigated in the research study. The distribution of fasting glucose (FG) was approximately normally distributed with mean 97 and standard deviation of 10. During 12 days, a sample of fifty students was selected. What is the probability that at least 6 students have FG < 87? Selected values of CDF (cumulative probabilities) for Binomial distributions are below. Please, justify your answer.
Question: During typical 5 years the average number of new cancer cases of certain type in Charlotte was 60. Assume that the number of new cancer cases can be well modeled using Poisson distribution. If conditions for the disease are similar during 2014, how high is the chance that 10 or more cases will be observed this year (use table on next page )? Justify your answer.
