Mr. Garcia's mean heart rate is 80 beats per minute, rounded to the nearest whole number.
To find the mean heart rate for Mr. Garcia's data set, you need to add up all the heart rates and divide by the number of data points.
Here is the calculation:
88 + 78 + 78 + 80 + 84 + 94 + 78 + 80 + 88 + 92 + 78 + 84 + 72 + 72 = ??? (sum of all heart rates)
Next, you need to divide the sum by the number of data points, which is 14 in this case (corresponding to the 14 dates). So:
???(sum of all heart rates) / 14 = ??? (mean heart rate)
Once you calculate the sum of all the heart rates, you divide it by 14 to get the mean heart rate. Finally, round the answer to the nearest whole number to get Mr. Garcia's mean heart rate.
To find the mean heart rate, we need to add up all the pulse values and divide by the number of data points.
Adding up the pulse values:
88 + 78 + 78 + 80 + 84 + 94 + 78 + 80 + 88 + 92 + 78 + 84 + 72 + 72 = 1178
There are 14 data points.
Dividing 1178 by 14:
1178 / 14 = 84.14285714285714
Rounding to the nearest whole number:
84.14285714285714 rounds to 84.
Therefore, Mr. Garcia's mean heart rate, rounded to the nearest whole number, is 84.
