Explain. O Yes, we observe a bell-shaped, symmetric distribution. No, we observe a uniform, skewed distribution. No, we observe a bell-shaped, skewed distribution. Yes, we observe a uniform, symmetric distribution. (b) Does the normal quantile plot indicate normality for the data distribution? Explain. Yes, the points do not fall on a straight line. O No, the points do not fall on a straight line. O No, the points fall approximately on a straight line. Yes, the points fall approximately on a straight line. (c) Compute the interquartile range. Check for outliers. O There are no outliers. There are no outliers, but two data points fall exactly on the boundary. O There are two outliers. There is one outlier. (d) Compute Pearson's index. (Round your answer to three decimal places.) Does the index value indicate skewness? Yes No e) Using parts (a) through (d), would you say the data are from a normal distribution? O No, the graphs do not support normality, there are no apparent outliers, but there is skewness. O Yes, the graphs su outliers, but there is skewness. O No, the graphs do not supp ewness, but there are apparent outliers. O Yes, the graphs support ent outliers, and there is no skewness. Submit
