The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1). For these 30 values, Q1 is the value at the 7.75th position (which is between the 7th and 8th values, so we average 171 and 172 to get 171.5), and Q3 is the value at the 22.75th position (which is between the 22nd and 23rd values, so we average 211 and 215 to get 213). The IQR = Q3 - Q1 = 213 - 171.5 = 41.5. However, since 41.5 is not an option and there seems to be a misunderstanding in the calculation or the options provided, the closest correct approach based on the options would be to reconsider the calculation or the interpretation of the options. Given the options, none directly match the calculated IQR, suggesting a potential error in the interpretation of the question or the provided options.
