Step-by-step explanation:

You will have to make a table, y and f(y), y will represent a point on X axis and f(y) will represent a point on the Y axis. In the table, add random points in the Y table <em>(</em><em>l</em><em>ike</em><em>,</em><em> </em><em>for</em><em> </em><em>example,</em><em> </em><em>-</em><em>3</em><em>,</em><em> </em><em>-</em><em>2</em><em>,</em><em> </em><em>-</em><em>1</em><em>,</em><em> </em><em>0</em><em>,</em><em> </em><em>1</em><em>,</em><em> </em><em>2</em><em>,</em><em> </em><em>3</em>). substitute by those Y values in the <u>X's</u> of the equation . Those results should be in the corresponding f(y) columns. After that, draw the curve.

So we have to start at 3.5 up the y axis. Then, we have to move 3 slots to the right. Let me know if this helps!

drug sniffing dogs must be 95% accurate in their responses because their handlers don't want them to miss durgs and also don't w
GenaCL600 [577]

Answer:

95% Confidence interval:  (0.8449,0.9951)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 50

Number of times the dog is right, x = 46

\hat{p} = \dfrac{x}{n} = \dfrac{46}{50} = 0.92

95% Confidence interval:

\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

Putting the values, we get:

0.92 \pm 1.96(\sqrt{\dfrac{0.92(1-0.92)}{50}})\\\\ = 0.92\pm 0.0751\\\\=(0.8449,0.9951)

(0.8449,0.9951) is the required 95% confidence interval for the proportion of times the dog will be correct.

anastassius [24]

Answer:

20 square inches

Step-by-step explanation:

Set width of sign to x.

Set length of sign to y.

5x=y

2(x+y)=24 inches

2(x+5x)=24 inches

12x=24 inches

width = 2 inches

length = 10 inches

Area = 20 square inches
