If g(n) varies inversely with n and g(n) = 8 when n = 3, find the value of n when g(n) = 6.

Anettt [7]

Answer:

Step-by-step explanation:

g(n) varies inversely with n.

This can be expressed alternatively as \[g(n) = \frac{k}{n}\] where k is a constant value.

Given that when n = 3, g(n) = 8.

This implies, \[8 = \frac{k}{3}\]

Simplifying the equation to solve for k, k = 8 * 3 = 24

Now when g(n) = 6, \[g(n) = \frac{k}{n}\]

\[6 = \frac{24}{n}\]

Calculating the value of n, \[n = \frac{24}{6}\] = 4

So the required value of n is 4.

Answer:

The 95 percent confidence interval for the population mean is between 14.736 tons and 16.864 tons.

Step-by-step explanation:

We have the population's standard deviation, so we can find the normal confidence interval.

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

$\alpha = \frac{1-0.95}{2} = 0.025$

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 $1-0.025 = 0.975$ , so $z = 1.96$

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.

$M = 1.96*\frac{3.8}{\sqrt{49}} = 1.064$

The lower end of the interval is the sample mean subtracted by M. So it is 15.8 - 1.064 = 14.736 tons

The upper end of the interval is the sample mean added to M. So it is 15.8 + 1.064 = 16.864 tons

The 95 percent confidence interval for the population mean is between 14.736 tons and 16.864 tons.
