Answer:

L = 3.975

Step-by-step explanation:

Given

See comment for data

Required

The lower limit 94% confidence interval

First, calculate the mean

\bar x =\frac{\sum x}{n}

\bar x =\frac{0.9+10+0.9+8.7+4.8+2.6+1+13.3+9.5+8.9+8.9+4.6}{12}

\bar x =\frac{74.1}{12}

\bar x =6.175

Next, calculate the standard deviation using:

\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}

So, we have:

\sigma = \sqrt{\frac{(0.9 - 6.175)^2 +(10- 6.175)^2 +.................+(8.9- 6.175)^2 +(4.6- 6.175)^2}{12}}

\sigma = \sqrt{\frac{197.2625}{12}}

\sigma = \sqrt{16.4385416667}

\sigma = 4.054

For 94% interval, the z score is

z = 1.88

So, the margin of error (E) is:

E = z * \frac{\sigma}{\sqrt n}

E = 1.88 * \frac{4.054}{\sqrt {12}}

E = 1.88 * \frac{4.054}{3.464}

E = 2.200

The confidence interval of the true mean is:

CI = (\bar x \± E)

The lower limit (L) is:

L = \bar x -E

L = 6.175 -2.200

L = 3.975

and the upper limit (U) is

U = \bar x + E

U = 6.175 + 2.200

U = 8.375

Triangle DBC is equilateral,<br>AB = AC. Work out the size of angle x. <br><br><br>Pls asap​
allochka39001 [22]

Answer:

x = 21º

Step-by-step explanation:

∆ ABC is isosceles therefor

Angles B and C are congruent

(180  - 18)/2 = 162/2 = 81º

------------------

∆ BCD is equilateral  therefor all angles are 60º

---------------------------

x = = 81 - 60

x = 21º
