1. The following data summarize the attendance records for a class of mathematics students. Classes Missed | Number of Students 0 | 0 1-3 | 7 4-6 | 12 7-9 | 5 10-12 | 3 13-15 | 2 a) Estimate the mean number of classes missed by students in this course. b) What is the median interval for the numbers of classes missed?

Step 1
To estimate the mean number of classes missed, we first need to find a representative value for each interval. This is typically done by finding the midpoint of each interval. Then, we multiply each midpoint by the number of students in that interval to get a Show moreā¦

(10 points total) Sample attendance records at school show the number of days each student was absent during the year: The days absent for each student were as follows: Calculate the mode, mean and the median speed. Which one of the three do you think better describes the data Set? Why? Mode (1 point) Median (1 point) Mean (2 point) Calculate the standard deviation of the sample. If necessary round your answer to three decimal places: (6 points)
