the following pulse rates were recorded for a group of 15 students. find the mean. 75, 77, 63, 65, 68, 61, 79, 68, 67, 62, 67, 72, 74, 83, 69\nthe mean is
Answer
Explanation:
Step1: Sum the data values
$75 + 77+63 + 65+68+61+79+68+67+62+67+72+74+83+69=1043$
Step2: Divide by number of data - points
The number of students (data - points) $n = 15$. The mean $\bar{x}=\frac{1043}{15}\approx69.53$
Answer:
$69.53$
