You are constructing a 95% confidence interval using the information: n = 60, x-bar = 65.5, s = 2.5, and E = 0.70. What is the v

elena-s [515]

Answer:

65.5

Step-by-step explanation:

Using the relation :

Xbar ± Margin of error

Margin of Error = Zcritical * s/√n

The Zcritical value at 95% = 1.96

Hence,

Margin of Error = 1.96 * 2.5/√60

Margin of Error = 1.96 * 0.3227486

Margin of Error = 0.6326

Lower boundary = 65.5 - 0.6326 = 64.867

Upper boundary = 65.5 + 0.6326 = 66.133

(64.867 + 66.133) / 2

Please help me do question 21, 22 and 23. I am in 6th grade.

Pachacha [2.7K]

Question 21: 24 minutes

$\frac{3}{\frac{3}{2} } = \frac{x}{12}$

x = $(\frac{3}{\frac{3}{2} })(12)$

x = 24

Question 22: 20 centimeters

x = one side of the square

x² = 25

x = 5

4x = perimeter

4(5) = perimeter

20 = perimeter

Question 23: 17 sides

Hexagon = 6 sides

Octagon = 8 sides

Triangle = 3 sides

Total amount of sides = 6 + 8 + 3

Total amount of sides = 17

I’m a little confused with this? Can someone walk me through this?

mina [271]

Answer:

A. 5.8

Step-by-step explanation:

From the given graph d has two coordinates;

the first coordinates of d = (0, 0)

the second coordinate of d = (-3 , -5), that is x = -3 when traced up and y = -5 when traced horizontal

The distance between the two coordinates = distance of d;

$distance \ between \ two \ coordinates = \sqrt{(x_2-x_1)^2 \ + \ (y_2-y_1)^2} \\\\d = \sqrt{(-3-0)^2 \ + \ (-5-0)^2}\\\\d = \sqrt{9 \ + \ 25} \\\\d = \sqrt{34} \\\\d = 5.83\\\\d = 5.8$

Option A is correct
