1).Randomly pick three blocks of five numbers and write them down.2).What sampling method did you just use? Describe the rationale for your answer in a paragraphof text.3).What is the probability that the next student taking the test would happen to select the samethree blocks of random numbers that you selected in number 1 above? Show your work so yourinstructor can provide feedback.4).Write down the last two digits of each of the 15 numbers selected in number 1 above. Presentthese numbers in an ordered stem and leaf plot.5).Using the data from number 4 above, construct a frequency distribution with an appropriatenumber of classes. Summarize the frequency distribution by presenting it in columns withheadings. Include headings for Class, Frequency, Midpoint, Relative Frequency, and CumulativeFrequency.6).Describe the distribution created by the data in number 4 and 5 above in terms of its shape,modality, skewness, etc., using appropriate statistical terminology7).Calculate the mean, variance and standard deviation of the distribution of scores listed innumber 4 above. Show your work so your instructor can provide feedback.8).Calculate the 50th percentile of the distribution in number 4 above. What score is at the 50thpercentile? Be sure to show your work.9).Based on what you know about the distribution above, what would be the probability ofselecting a score at random that corresponds to a z-score of at least 1.4?
