Question
ge ensnce that a randomly selected individual from this population would give a response between 6.9 and 8.2 days 3. Clinical literature reports that the duration of a ty cold is roughly 18 days. Researchers wanted to know if people tend to underestimate the duration of a typical cold, on average. Th cold lasts. The researchers reported a 9s% condence intervai of 6.9 to 8. pical surveyed a random sample of 352 healthy adults in Georgia and asked them how long they think that a typical The researchers days for the mean expected duration of typical cold. The researchers reported that the answers to this question were strongly vight-skewed. The9 O not appropriate because the sample data are skewed O not appropriate because the answers of all healthy adults in Georgia are ikely not Normally distributed. kely appropriate because the answers of all healthy adults in Georgia are likely to be Normally distributed given that this is such a large population. S% confidence interval (6.9. 8.2) they obtained appropriate despite the skewed data because the sample size is large enough to rely on the robustness of the t procedures.Explanation / Answer
Solution:-
option D. approprlate despite the skewed data because the sample size is large enough to rely on the rebustness of the t procedures.
