Afina-wow [57]

$\frac{1}{11}+\frac{1}{15}=\frac{1\cdot15}{11\cdot15}+\frac{1\cdot11}{15\cdot11}=\frac{15}{165}+\frac{11}{165}=\frac{15+11}{165}=\frac{26}{165} < \frac{1}{2}\\\\\frac{1}{11}+\frac{1}{15}\approx0$

Answer: 0.0228

Step-by-step explanation:

Given : The mean and the standard deviation of finish times (in minutes) for this event are respectively as :-

$\mu=30\\\\\sigma=5.5$

If the distribution of finish times is approximately bell-shaped and symmetric, then it must be normally distributed.

Let X be the random variable that represents the finish times for this event.

z score : $z=\dfrac{x-\mu}{\sigma}$

$z=\dfrac{19-30}{5.5}=-2$

Now, the probability of runners who finish in under 19 minutes by using standard normal distribution table :-

$P(X$

Hence, the approximate proportion of runners who finish in under 19 minutes = 0.0228
