The data set below contains the total cost (in dollars) of attending 26 different professional sporting events in a recent year. Complete parts (a) and (b). 233 212 160 170 220 188 195 227 196 245 203 219 271 D 182 235 155 239 200 249 265 219 156 200 204 196 210 a. Decide whether the data appear to be approximately normally distributed by comparing data characteristics to theoretical properties. Based on the theoretical properties of the normal distribution, do the data appear to be approximately normally distributed? O A. No, because there are a significant number of outliers. O B. No, because the distribution of the data is significantly skewed to the right. OC. No, because the distribution of the data is significantly skewed to the left. O D. Yes, the distribution of the data appears to closely resemble a normal distribution. ɔ. Decide whether the data appear to be approximately normally distributed by using the descriptive statistics you computed with a statistical application (like Analysis Toolpak, StatPlus, or StatCrund What is the best description of the given data based on the descriptive statistics? O A. The data are skewed to the left because the range is 6 times the standard deviation. O B. The data appear to be normally distributed since mean and median are nearly the same. O C. The data are skewed to the right since the IQR is nearly 1.33 standard deviations.

Transcribed Image Text:The data set below contains the total cost (in dollars) of attending 26 different professional sporting events in a recent year. Complete parts (a) and (b).
233 212 160 170 220 188 195 227 196 245 203 219 271 O
182 235 155 239 200 249 265 219 156 200 204 196 210
a. Decide whether the data appear to be approximately normally distributed by comparing data characteristics to theoretical properties.
Based on the theoretical properties of the normal distribution, do the data appear to be approximately normally distributed?
O A. No, because there are a significant number of outliers.
O B. No, because the distribution of the data is significantly skewed to the right.
OC. No, because the distribution of the data is significantly skewed to the left.
O D. Yes, the distribution of the data appears to closely resemble a normal distribution.
b. Decide whether the data appear to be approximately normally distributed by using the descriptive statistics you computed with a statistical application (like Analysis Toolpak, StatPlus, or StatCrunch).
What is the best description of the given data based on the descriptive statistics?
O A. The data are skewed to the left because the range is 6 times the standard deviation.
O B. The data appear to be normally distributed since mean and median are nearly the same.
O C. The data are skewed to the right since the IQR is nearly 1.33 standard deviations.
