Question

the following data represents the age of 30 lab technicians. copy data to clipboard 24 79 61 66 25 67 30 42 34 66 78 30 76 40 36 30 47 40 40 37 40 70 49 65 66 51 42 40 28 89 use the frequency distribution tool to determine the frequency distribution of th age frequency 20 - 29 30 - 39 40 - 49 50 - 59 60 - 69 70 - 79 80 - 89

Explanation:

Step1: Count data in 20 - 29

Count numbers between 20 and 29 in the data set. The numbers are 24, 25, 28. So the frequency is 3.

Step2: Count data in 30 - 39

Count numbers between 30 and 39. The numbers are 30, 34, 30, 36, 30, 37. So the frequency is 6.

Step3: Count data in 40 - 49

Count numbers between 40 and 49. The numbers are 42, 40, 47, 40, 40, 49, 42, 40. So the frequency is 8.

Step4: Count data in 50 - 59

Count numbers between 50 and 59. The number is 51. So the frequency is 1.

Step5: Count data in 60 - 69

Count numbers between 60 and 69. The numbers are 61, 66, 66, 67, 66, 65. So the frequency is 6.

Step6: Count data in 70 - 79

Count numbers between 70 and 79. The numbers are 79, 78, 76, 70. So the frequency is 4.

Step7: Count data in 80 - 89

Count numbers between 80 and 89. The number is 89. So the frequency is 1.

Answer:

Age	Frequency
30 - 39	6
40 - 49	8
50 - 59	1
60 - 69	6
70 - 79	4
80 - 89	1
