navik [9.2K]

Answer:

Step-by-step explanation:

the given data is

93 43 50 48

the range is given by the following formula :

Range = Vmax - Vmin

where

Vmax= maximum value of Data

Vmin= minimum value of Data

from the given data ,

Vmax = 93 and Vmin = 43

hence,

Range = 93 - 43

Range = 50

Find the area of the triangle. Figure is not drawn to scale. Show your work. (Image attached)

Zolol [24]

Answer: $13.8cm^2$

Step-by-step explanation:

The area of a triangle can be calculated with the formula:

$A_{(triangle)}=\frac{b*h}{2}$

The base of the triangle is "b" and the height of the triangle is "h",

In the figure you can observe that the base and the height of the triangle are:

$b=6.9cm\\h=4cm$

Knowing these values, you can substitute them into $A_{(triangle)}=\frac{b*h}{2}$ .

Therefore, the area of the triangle is:

$A_{(triangle)}=\frac{(6.9cm)(4cm)}{2}$

$A_{(triangle)}=13.8cm^2$

The confidence interval is (-1.1059, 7.70459).

<h3>What is confidence interval in statistics?</h3>

Image result for what is confidence interval

A confidence interval is the mean of your estimate plus and minus the variation in that estimate.

The sample mean is M=3.3

The sample size is N=44

So, σM= s/√N = 16.6/ √44

= 16.6/ 6.633

= 2.621

and, the degree of freedom

df= n-1

=44-1

=43

So, The t-value for a 90% confidence interval and 43 degrees of freedom is t=1.681.

Now, Margin of error = 2.261* 1.681 = 4.4059

Now, the lower and upper bound of the confidence interval are:

LL = 3.3- 4.40459 = -1.1059

UL = 3.3+ 4.40459 = 7.70459

Hence, the confidence interval is (-1.1059, 7.70459).
