The diagram below shows the normal probability plot and box-and-whiskers plot for a simple random sample of size n < 30. Determine whether a t-interval should be constructed. (circle one answer) n = 15, Correlation = 0.893 1.5 1 0.5 Expected z-Score 0 -0.5 -1 . -1.5 . 0 2 6. 8. 10 0 2 4 6 8 10 X Is the assumption of the normality of the sample data satisfied? (a) Yes, because the normal probability plot does not show a linear pattern in the data and the box-and-whiskers plot shows more than one outlier. (6) No, because normal probability plot does not show a linear pattern in the data and the box-and-whiskers plot shows more than one outlier. (c) Yes, because the normal probability plot is roughly linear and the box-and-whiskers plot shows more than one outlier. (d) No, because the normal probability plot is roughly linear and the box-and-whiskers plot shows more than one outlier.
