For this assignment, you will be analyzing the educational transitions for a sample of Irish schoolchildren aged 11 in 1967. Focus on the variable DVRT (Drumcondra Verbal Reasoning Test Score) only. Make sure that when you do your analysis you are analyzing this variable and not another mistakenly. Using the data provided, answer the following questions and provide the requested analysis. 1) Construct a dotplot depicting the distribution of DVRT scores in the sample. 2) Based on the dotplot constructed in part (1), is it reasonable to conclude the DVRT scores follow a Normal distribution? Justify your answer. For parts (3) - (5), assume the variance of the DVRT scores in the population of 11 year old Irish School Children is 200. 3) Construct a 90% Confidence Interval for the mean DVRT score in the population. 4) Calculate the precision of the 90% Confidence Interval for the mean DVRT scores constructed in part (3). 5) How many students would need to be sampled in order to achieve a precision of 1 at a level of confidence of 95%?
