A city planner wants to estimate the average monthly residential water usage in the city. He selected a random sample of 100 hou
hodyreva [135]

Answer:

The 90% confidence interval for the average monthly residential water usage for all households in this city is between 4401.3 gallons and 4598.7 gallons.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.05 = 0.95, so z = 1.645

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.645*\frac{600}{\sqrt{100}} = 98.7

The lower end of the interval is the sample mean subtracted by M. So it is 4500 - 98.7 = 4401.3 gallons

The upper end of the interval is the sample mean added to M. So it is 4500 + 98.7 = 4598.7 gallons

The 90% confidence interval for the average monthly residential water usage for all households in this city is between 4401.3 gallons and 4598.7 gallons.

Rewrite each fraction with a denominator of 10 7/2 3/5
Vaselesa [24]

Answer:

  • \frac{7}{2}=\frac{35}{10}
  • \frac{3}{5}=\frac{6}{10}

Step-by-step explanation:

Given the fraction

\frac{7}{2}

Multiplying numerator and denominator by 5

\frac{7}{2}\times \frac{5}{5}

=\frac{35}{10}

Therefore,

  • \frac{7}{2}=\frac{35}{10}

Similarly,

Given the fraction

\frac{3}{5}

Multiplying numerator and denominator by 2

\:\frac{3}{5}\times \:\frac{2}{2}

\frac{3}{5}\times \:\frac{2}{2}=\frac{6}{10}

Therefore,

  • \frac{3}{5}=\frac{6}{10}
