The accompanying data represent the miles per gallon of a random sample of cars with a three-cylinder, 1.0 liter engine. (a) Compute the z-score corresponding to the individual who obtained 34.3 miles per gallon. Interpret this result. (b) Determine the quartiles. (c) Compute and interpret the interquartile range, IQR. (d) Determine the lower and upper fences. Are there any outliers? Click the icon to view the data. (a) Compute the z-score corresponding to the individual who obtained 34.3 miles per gallon. Interpret this result. The z-score corresponding to the individual is O and indicates that the data value is standard deviation(s) (Type integers or decimals rounded to two decimal places as needed.) the O MPG Data 38.0 42.5 42.7 32.7 35.9 38.7 39.1 39.5 39.9 34.3 36.2 38.1 40.6 34.5 37.3 38.2 41.4 43.8 35.7 37.5 38.5 39.7 41.5 48.9

A large, multi-company construction workers union is gathering data on the number of workplace injuries that occurred last year. It gathers the number of injuries from 20 randomly selected companies among the hundreds of construction companies at which its members work. The data are provided below. Use Excel and the QUARTILE.INC function to construct a box and whisker plot for the dataset. What is the value of the median? Round your answer to one decimal place. Number of on the job injuries 133333220324312076417 109328 30

Because the mean is very sensitive to extreme values, it is not a resistant measure of center. By deleting some low values and high values, the trimmed mean is more resistant. To find the 10% trimmed mean for a data set, first arrange the data in order, then delete the bottom 10% of the values and delete the top 10% of the values, then calculate the mean of the remaining values. Use axial loads (pounds) of aluminum cans listed below for cans that are 0.0111 in. thick. Identify any outliers, then compare the median, mean, 10% trimmed mean, and 20% trimmed mean. 247 261 269 273 275 280 282 282 284 285 285 287 290 292 293 296 296 299 311 507 Identify any outliers. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The outlier(s) is/are pounds. (Type a whole number. Use a comma to separate answers as needed.) C OB. There are no outliers.
