Answer:

combine -3-1

- 2x - 14 =  - 4

if you want to solve for x then you would move the -14 to the left buy adding 14 to both sides.

- 2x - 14 =  - 4 \\    \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  + 14 \:  \:  + 14

your equation there will be

- 2x = 10

then you will divide -2 on both sides

\frac{ - 2x}{ - 2}  =  \frac{10}{ - 2}

finally x will equal

x =  - 5

The diameter of holes for a cable harness is known to have a normal distribution with σ = 0.01 inches. A random sample of size 1
Rama09 [41]

Answer: (1.4964, 1.5126)

Step-by-step explanation:

We know that the confidence interval for population mean is given by :-

\overline{x}\ \pm z*\dfrac{\sigma}{\sqrt{n}}

, where {\sigma= population standard deviation.

n= sample size

\overline{x} = Sample mean

As per given , we have

σ = 0.01 inches

n= 10

\overline{x}=1.5045

Also, the critical value for 99% confidence interval = z*=2.576 [From x-value table.]

[Significance level =1-0.99=0.01 and z_{\alpha/2}\ at\ \alpha=0.01 is 2.576.]

Then, the 99% two-sided confidence interval on the mean hole diameter will be :-

1.5045\ \pm (2.576)\dfrac{0.01}{\sqrt{10}}\\\\\approx1.5045\pm(2.576)(0.00316)=1.5045\pm0.00814016=(1.5045-0.00814016,\ 1.5045+0.00814016)\\\\=(1.49635984,\ 1.51264016)\approx(1.4964,\ 1.5126)

Hence, the required confidence interval = (1.4964, 1.5126)
