After exercise, the pulse rate tends to decrease as the body recovers from the physical activity. A lower pulse rate indicates that the heart is functioning efficiently and pumping blood effectively. Therefore, 59 is the lowest pulse rate after exercise among the given options.

The heaviest weight recorded is 103 kg, as stated in all three options.

The answer is 18 because it is stated that there are 18 students who scored higher than 75%.

The mode for the data set is 26. This means that 26 is the value that appears most frequently in the data set.

The range of the students' heights is 86-111 cm. This means that the shortest student is 86 cm tall and the tallest student is 111 cm tall.

According to the given data, the statement that non-smokers are generally heavier than smokers is false.

Most of the children's heights lie in the range of 90-100 cm. This suggests that the majority of children are within this height range, indicating a common height distribution among children.

The median number of birds visiting the feeder each day is 25. This means that when all the daily bird counts are arranged in ascending order, the middle value is 25. This indicates that there are an equal number of days where the bird count is higher and lower than 25.

The median value for class B is 72. This means that when all the values in class B are arranged in ascending order, the middle value is 72. In other words, 72 is the value that separates the lower half of the values from the upper half, with an equal number of values on either side.

The highest pulse rate before exercise is 79. This means that before engaging in physical activity, the person's heart rate reached a maximum of 79 beats per minute.

The median arm span refers to the middle value when all the arm spans are arranged in ascending order. Since the given options are 9 cm, 139 cm, and 13 cm, the median arm span would be the middle value, which is 139 cm.

The answer is 4 because the question asks how many students were graded a C, and the number 4 is the only option that represents a quantity of students. The other options, 5 and 86441, do not make sense in the context of the question.
