the frequency distribution below represents frequencies of actual low temperatures recorded during the course of a 31 - day month. use the frequency distribution to construct a histogram. do the data appear to have a distribution that is approximately normal?\n| class | frequency |\n| a 30 - 34 | 1 |\n| b 35 - 40 | 1 |\n| c 41 - 46 | 7 |\n| d 47 - 52 | 11 |\n| e 53 - 58 | 5 |\n| f 59 - 64 | 3 |\n| g 65 - 70 | 3 |\nchoose the correct histogram below\no a.\no b.\no c.\no d.
Answer
Explanation:
Step1: Identify class - frequency pairs
We have the following class - frequency pairs: A (30 - 34) with frequency 1, B (45 - 50) with frequency 1, C (51 - 56) with frequency 7, D (57 - 62) with frequency 11, E (63 - 68) with frequency 5, F (69 - 74) with frequency 3, G (75 - 80) with frequency 3.
Step2: Analyze histogram options
We check each histogram option to see which one has the correct bar - heights corresponding to the frequencies of each class. For option A: The bar - heights do not match the given frequencies. For option B: The bar - heights do not match the given frequencies. For option C: The bar - heights match the frequencies 1, 1, 7, 11, 5, 3, 3 for classes A, B, C, D, E, F, G respectively. For option D: The bar - heights do not match the given frequencies.
Answer:
C
