I cant see all of 11 and 14
12:
3f = 18 \\   \frac{3f}{3}  =  \frac{18}{3}  \\ f = 6
13:
3f =  {3}^{2}  \\ 3f = 9 \\  \frac{3f}{3}  =  \frac{9}{3}  \\ f = 3
15:
3h = 9 + 10 \\ 3h = 19 \\  \frac{3h}{3}  =  \frac{19}{3}  \\ h = 6.3
16:
3f = 27 - 21 \\ 3f = 6 \\  \frac{3f}{3}  =  \frac{6}{3}   \\ f = 2

Valentin [98]

Answer:

The 95% confidence interval for the mean is between 0.985g/cm² and 1.047 g/cm².

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{1-0.95}{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 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{0.155}{\sqrt{94}} = 0.0310

The lower end of the interval is the mean subtracted by M. So it is 1.016 - 0.0310 = 0.985 g/cm²

The upper end of the interval is the mean added to M. So it is 1.016 + 0.0310 = 1.047 g/cm²

The 95% confidence interval for the mean is between 0.985g/cm² and 1.047 g/cm².
