2. The following data was collected on pupil dilation diameters from a new test being considered for reducing cornea recovery time from surgeries. 1.21cm 0.63cm 1.08cm 0.21cm 0.97cm 1.11cm 1.08cm 1.25cm 1.15cm 0.91cm 1.37cm 1.04cm 1.23cm 0.75cm 1.05cm 0.98cm 1.17cm 1.17cm 1.17cm 1.06cm 1.21cm 1.0cm 1.31cm 0.99cm 1.13cm (a) Present the data based on the first half of this course and make any observations. (b) At 80% confidence, construct a confidence interval to predict the average pupil dilation diameters for this data? (e) Repeat this for 98% confidence. (d) Repeat this for 95% confidence. (@) Were any assumptions needed to answer the above questions. Why or why not
