The amount of water person typically drinks in a week has a mean of 100 ounces and a standard deviation of 15 ounces. Using the
e-lub [12.9K]

Solution: We are given:

\mu=100,\sigma=15

We have to find the amount of water that represents the top 97.5%.

We need to find the z value corresponding to probability to 0.975. Using the standard normal table, we have:

z(0.975)=1.96

Now using the z score formula, we have:

z=\frac{x-\mu}{\sigma}

1.96=\frac{x-100}{15}

1.96 \times 15 = x-100

29.4=x-100

x=100+29.4 = 129.4

Therefore, 129.4 ounces amount of water represents the top 97.5%
