The slope will be the same as the equation 6x-y=1 because they are parallel to each other, meaning that they will never touch each other. So then slips will be 6. The number attached to the x will always be the slope. Equation formula is y=mx+b. M is slope.

So use -a/b and you get 6x as the slope and the parallel line would have the same slope

Marizza181 [45]

Answer:

a) X^ = 70 GPa , s = 0.4 GPa

b) X^ = 70 GPa , s = 0.2 GPa

c) n = 64 .. part b

Step-by-step explanation:

Solution:-

- A sample ( n ) was taken from aluminum alloy sheets of a particular type the distribution parameters are given below:

                      Mean ( u ) = 70 GPa

                      Standard deviation ( σ ) = 1.6 GPa

a)

- We take a sample size of n = 16. The random variable X denotes the distribution of the sample obtained.

- We will estimate the parameters of the sample distribution X.

- The point estimate method tells us that the population mean ( u ) is assumed as the sample mean ( X^ ).

                    Sample Mean ( X^ ) = u = 70 GPa

- The sample standard deviation ( s ) for the given sample with known population standard deviation ( σ ) is given by:

                   sample standard deviation ( s ) = σ / √n

                   sample standard deviation ( s ) = 1.6 / √16

                   sample standard deviation ( s ) = 0.4 GPa

b)

Repeat the above calculations for sample size n =  64.

- We will estimate the parameters of the sample distribution X.

- The point estimate method tells us that the population mean ( u ) is assumed as the sample mean ( X^ ).

                    Sample Mean ( X^ ) = u = 70 GPa

- The sample standard deviation ( s ) for the given sample with known population standard deviation ( σ ) is given by:

                   sample standard deviation ( s ) = σ / √n

                   sample standard deviation ( s ) = 1.6 / √64

                   sample standard deviation ( s ) = 0.2 GPa

c)

- The standard deviation ( s ) gives us the uncertainty of mean ( X^ ). How spread apart/close are the data points from the mean.

- We see that standard deviation ( s ) has an inverse relation to the sample size ( n ):

                   sample standard deviation ( s ) = σ / √n

- So with increasing sample size the there is a decreased variability in the sample distribution of ( X ).

Answer: The sample size n = 64 used in part b would give us lesser variability of sample distribution of X as compared to sample size n = 16 used in part a. Hence, X is more likely to be within 1 GPa of the mean in part (b). This is due to the decreased variability
