I can help you with analyzing the data provided for waist measurements. Let's address each part of the question:
a) To find how many men have a waist measurement of more than 85 cm, you need to look at the cumulative frequency table. Check the cumulative frequency corresponding to the waist measurement of 85 cm and subtract that value from the total number of men to get the number of men with a waist measurement greater than 85 cm.
b) The median waist measurement represents the middle value when the data is arranged in ascending order. If the total number of men is even, you would take the average of the two middle values to find the median.
c) The interquartile range is calculated by finding the difference between the first quartile (Q1) and the third quartile (Q3). To determine Q1 and Q3, you need to locate the 25th and 75th percentiles in the cumulative frequency table and then find the corresponding waist measurements.
By following these steps and using the provided data, you can accurately determine the number of men with a waist measurement greater than 85 cm, the median waist measurement, and the interquartile range of the waist measurements.
