hammer [34]

Answer:

The rate of change of f(x) with respect to x is 1/4

Step-by-step explanation:

What this question simply ask is to find the slope of the line that passes through the two points

to find this, we use the slope equation

we have this as;

m= (y2-y1)/(x2-x1)

(x1,y1) = ((-15,-3)

(x2,y2) = (-7,-1)

m = (-1 + 3)/(-7 + 15) = 2/8 = 1/4

Do one of the​ following, as appropriate.​ (a) Find the critical value z Subscript alpha divided by 2​, ​(b) find the critical v
babymother [125]

Answer:

We want to construct a confidence interval at 99% of confidence, so then the significance level would be 1-0.99 =0.01 and the value of \alpha/2 =0.005. And for this case since we know the population deviation is not appropiate use the t distribution since we know the population deviation and the best quantile assuming that the population is normally distributed is given by the z distribution.

And if we find the critical value in the normal standard distribution or excel and we got:

z_{\alpha/2}= \pm 2.576

And we can use the following excel code:

"=NORM.INV(0.005,0,1)"

Step-by-step explanation:

For this case we have the following info given:

\alpha=0.01, n =26, \sigma = 28.9

We want to construct a confidence interval at 99% of confidence, so then the significance level would be 1-0.99 =0.01 and the value of \alpha/2 =0.005. And for this case since we know the population deviation is not appropiate use the t distribution since we know the population deviation and the best quantile assuming that the population is normally distributed is given by the z distribution.
