Question

a group of 150 students were asked to identify 55 flowers. the relative frequency table shows the results. about how many students identified at least 35 flowers?

Answer 1

5+31+19= 55 so D is your answer 

Answer 2

55 Students identified at least 35 flowers.

Explanation:

Here we have to ask at least 35 flowers, so there are only 3 classes. i.e. 35 - 41, 42 - 48, 49 - 55.

Thus, Number of Students identified at least 35 flowers is: 5 + 31 + 19 = 55

Further, Frequency is the number of repetitions of particular observation or class.

Relative frequency is the proportion of frequency. For finding the Relative Frequency divide the frequency of that observation or class to the total frequencies.
