gayaneshka [121]

Answer:

(832.156, \ 847.844)

Step-by-step explanation:

Given data :

Sample standard deviation, s = 15

Sample mean, \overline x = 840

n = 23

a). 98% confidence interval

$\overline x \pm t_{(n-1, \alpha /2)}. \frac{s}{\sqrt{n}}$

$E= t_{( n-1, \alpha/2 )} \frac{s}{\sqrt n}}

$t_{(n-1 , \alpha/2)} \frac{s}{\sqrt n}$

$t_{(n-1, a\pha/2)}=t_{(22,0.01)} = 2.508$

∴ $E = 2.508 \times \frac{15}{\sqrt{23}}$

  $E = 7.844$

So, 98% CI is

$(\overline x - E, \overline x + E)$

(840-7.844 ,  \ 840+7.844)

(832.156, \ 847.844)

Pie

Using translation concepts, the coordinates that will best represent point E′ are given by:

D. (11, 1).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the rule to find the image of a point (x,y) is given by:

(x, y) → (x + 8, y + 5).

Then, the rule to find the image E' of point E(3,-4) is given by:

(3,4 -> (3 + 8, -4 + 5) = (11,1).

Hence option D is correct.

Day 1 = $0.10

Day 2 = $0.10 + double the last fine which is $0.20 = $0.30

Day 3 = $0.30 + $0.30 = $0.60

Day 5 = $0.60 + $0.30 = $0.90
