A sample of 56 employees was taken to determine average pulse rate. The data is in the table below: The mode(s) is/are_______. Pulse Rate (beats per minute) Frequency (# of employees) pulse rate(beats per min) Frequency(# of employees)
54 1
58 4
65 7
68 9
72 4
76 10
80 12
84 4
90 3
98 2
The mode is the value that appears most often
That is the value that appears more number of times
From the above data
The value ' 80 ' appears 12 times
80 is the most appeard value
Mode = 80

Use the accompanying data set on the pulse rates (in beats per minute) of males to complete parts (a) and (b) below. LOADING... Click the icon to view the pulse rates of males. a. Find the mean and standard deviation, and verify that the pulse rates have a distribution that is roughly normal. The mean of the pulse rates is 71.871.8 beats per minute. (Round to one decimal place as needed.) The standard deviation of the pulse rates is 12.212.2...

Body Exam measurements are from 300 subjects. Age is in years, GENDER 1 = Male 0 = Female. PULSE is the pulse rate (beats per minute), SYSTOTOLIC is systolic blood pressure (mmHg). DIASTOLIC is diastolic blood pressure (mmHG), HDL is cholesterol (mg/dL). LDL is LDL cholesterol (Hg/dL). WHITE is the white blood cell count (1000cells/μL). RED is red blood cell count (million cells/ μL), PLATE is platelet count (1000cells/μL). WEIGHT is weight (kg), HEIGHT is height (cm), WAIST is waist...
