Oliga [24]

Answer:

99% Confidence interval: (50.9,61.3)

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = 56.1

Sample size, n = 72

Alpha, α = 0.01

Sample standard deviation, σ = 16.7

Degree of freedom = n - 1 = 71

99% Confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 71 and}~\alpha_{0.01} = \pm 2.64$

$56.1 \pm 2.64(\dfrac{16.7}{\sqrt{72}} ) \\\\= 56.1 \pm 5.19\\\\ = (50.91 ,61.29)\approx (50.9,61.3)$

Plot a graph of the line y = x - 3. Help please ASAP!

eduard

Step-by-step explanation:

An easy way to plot two points and connect them with line

Point 1

x = 0, this gives us y = - 3
So (0, - 3)

Point 2

x = 3, this gives us y = 0
So (3, 0)

Now plot these two points to get the line
