Answer:
the time Ari spent to walk is
the time Beth spent to walk is
the time Cathy spent to walk is 1h21' = 1.35(h)
so the time Ari spent > Cathy > Beth
=> list: Beth, Cathy, Ari
Using the Empirical Rule, it is found that standard deviation of the sample proportions is of 0.058.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
0.684 and 0.916 is within 2 standard deviations of the mean(below and above), hence there are 4 standard deviations between these measures, so:
4s = (0.916 - 0.684)
s = (0.916 - 0.684)/4
s = 0.058.
