anastassius [24]

Answer:

23.9 (rounded)

Step-by-step explanation:

First find the mean of all the numbers

this is 79.3

then find the distance from every number from the mean

15- 64.3

60- 19.3

90- 10.7

90- 10.7

100- 20.7

100- 20.7

100- 20.7

then find the average of the distances

which is 23.9

Complete Question

The complete question is shown on the first uploaded image

Answer:

The confidence interval is $64.86$

Step-by-step explanation:

From the question we are given the following data

The following heights are

66, 65, 67, 62, 62, 65, 61, 70, 66, 66, 71, 63, 69, 65, 71, 66, 66, 69, 68, 62, 65, 67, 65, 71, 65, 70, 62, 62, 63, 64, 67, 67

The sample size is n =32

The confidence level is $k = 95$ % = 0.95

The mean is evaluated as

$\= x = 66+ 65+ 67+ 62+ 62+ 65+ 61+ 70+ 66+ 66+ 71+63+ 69+ 65+ 71+ 66+ 66+ 69+ 68+ 62+ 65+ 67,+\\65+ 71+ 65+ 70+ 62+ 62+ 63+ 64+ 67+ 67 / 32$

=> $\= x = \frac{2108}{32}$

=> $\= x = 65.875$

The standard deviation is evaluated as

$\sigma = \sqrt{ v}$

Now

$v = ( 66-65.875 )^2+(65-65.875)^2+( 67-65.875)^2+ (62-65.875)^2+ (62-65.875)^2+ (65-65.875)^2+( 61-65.875)^2+ (70-65.875)^2+ (66-65.875)^2+ (66-65.875)^2+ (71+63-65.875)^2+ (69-65.875)^2+ (65-65.875)^2+ (71-65.875)^2+( 66-65.875)^2+ (66-65.875)^2+ (69-65.875)^2+ (68-65.875)^2+ (62-65.875)^2+ (65-65.875)^2+ (67-65.875)^2,+\\(65-65.875)^2+ (71-65.875)^2+ (65-65.875)^2+ (70-65.875)^2+( 62-65.875)^2+( 62-65.875)^2+ (63-65.875)^2+ (64-65.875)^2+ (67-65.875)^2+ (67-65.875)^2 / 32$

=> $v= 8.567329$

=> $\sigma = \sqrt{8.567329}$

=> $\sigma = 2.927$

The level of significance is evaluated as

$\alpha = 1 - 0.95$

$\alpha = 0.05$

The degree of freedom is evaluated as

$Df = n- 1 \equiv Df = 32 -1 = 31$

The critical values for the level of significance is obtained from the z -table as

$t_c = t_{\alpha/2 } , Df = t _{0.05/2}, 31 =\pm 1.96$

The confidence interval is evaluated as

$\mu = \= x \pm t_c * \frac{\sigma }{\sqrt{n} }$

substituting values

$\mu =65.875 \pm 1.96* \frac{2.927}{\sqrt{32} }$

$\mu =65.875 \pm 1.01415$

=> $64.86$

Right angle<br>The sum of yo and 50° is a right<br>find the value of yo. [4]<br>then

abruzzese [7]

Answer:

The angle yo measures 40º.

Step-by-step explanation:

Given that the sum of yo and 50 ° is a right angle, to find the value of yo the following calculation must be performed, knowing that a right angle measures 90 °:

50 + yo = 90

yo = 90 - 50

yo = 40

Therefore, the angle yo measures 40º.
