Using the given points, determine the slope. (8, 1) and (8, -4) slope = 0 slope = -5 slope is undefined
Sophie [7]
You find the slope by putting the points in the formula y2-y1/x2-x1

when you plug them in it should look like this

-4 -1/8-8
then you would add or subtract, when you do you would get

-5/0 
this can't be divide so the slope of this 2 points is undefined

Hope this helped

You measure 44 textbooks' weights, and find they have a mean weight of 51 ounces. Assume the population standard deviation is 11
elena-14-01-66 [18.8K]

Answer: (47.51, 54.49)

Step-by-step explanation:

Confidence interval for population mean is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

, where n= sample size .

\sigma = population standard deviation.

\overline{x} = sample mean

z_{\alpha/2} = Two -tailed z-value for {\alpha (significance level)

As per given , we have

\sigma=11.8\text{ ounces}

\overline{x}=51 \text{ ounces}

n= 44

Significance level for 95% confidence = \alpha=1-0.95=0.05

Using z-value table ,

Two-tailed Critical z-value : z_{\alpha/2}=z_{0.025}=1.96

Now, the 95% confidence interval for the true population mean textbook weight will be :-

51\pm (1.96)\dfrac{11.8}{\sqrt{44}}\\\\=51\pm(1.96)(1.7789)\\\\=51\pm3.486644\approx51\pm3.49\\\\=(51-3.49,\ 51+3.49)\\\\=(47.51,\ 54.49)

Hence, the 95% confidence interval for the true population mean textbook weight. :  (47.51, 54.49)
