Why is it important to know this when determining the type of confidence interval you may construct? Pitch speed is a variable. This is important to know because confidence intervals for a variable are constructed on quantitative data. The data could come from a population that is normally distributed. Which normal probability plot represents the data? A. B. C. D. Draw a boxplot to verify the data set has no outliers. Which boxplot below represents the data? A. B. C. D. What condition must the pitch speed of the pitcher's four-seam fastball satisfy?

1. A t-interval cannot be constructed because there is an outlier.
2. A t-interval can be constructed because there are outliers and the data can reasonably be assumed to come from a normal distribution.
3. A t-interval cannot be constructed because the data cannot reasonably be assumed to come from a normal distribution.
4. A t-interval can be constructed because there are no outliers and the data can reasonably be assumed to come from a normal distribution.
