Question

a nurse decides to run a simulation on the weights of the next 15 babies that will be born in her hospital. the simulation uses values from 5 to 10 pounds. based on the simulation results, estimate the probability of a baby being born between 7.0 and 8.0 pounds. 8.9 7.1 7.0 5.3 6.8 5.5 9.7 7.5 5.0 5.3 5.1 7.3 8.5 7.5 9.7 (1 point) 0.533 0.067 0.333 0.467

Explanation:

Step1: Count the total number of data points

There are \(n = 15\) data points.

Step2: Count the number of data points in the range \(7.0 - 8.0\)

The values in the range \(7.0 - 8.0\) are \(7.1\), \(7.0\), \(7.5\), \(7.3\), \(7.5\). So \(m=5\)

Step3: Calculate the probability

The probability \(P=\frac{m}{n}\). Substituting \(m = 5\) and \(n=15\), we get \(P=\frac{5}{15}=\frac{1}{3}\approx0.333\)

Answer:

\(0.333\) (the third option)
