Simplify <img src="https://tex.z-dn.net/?f=%5Csqrt%20-25" id="TexFormula1" title="\sqrt -25" alt="\sqrt -25" align="absmiddle" c
garik1379 [7]

Answer:

5<em>i</em>

Step-by-step explanation:

  1. = \sqrt{-1 * 25}
  2. = \sqrt{-1}\sqrt{25}
  3. = \sqrt{-1} * 5

Rule: \sqrt{-1} = <em>i</em>

So you get <em>i  </em>* 5<em> </em>=<em> </em>5<em>i</em>

If a particular set of data is approximately normally distributed, we would find that approximately A) 2 of every 3 observations
Kryger [21]

Answer:

A) No

B) No

C) Yes

Step-by-step explanation:

A)  2 out of three observations is equal to

2/3  = 0.67    or  67 %

We know tha the interval

[μ  -  σ/2 ,  μ + σ/2]  is approximately 68.3 % of the values

Therefore 2 out of 3 would not fall in that interval

B)

4 out of  5   is  4/5    = 0,8     or 80 %  If we  examine the interval

[μ  -  σ ,  μ + σ ]   which is approximately 95. Then value 4/5  ( 0,8)

Therefore 0,8 is out of the interval

C) 19/20 = 0,95     or 95 % is almost exact the value for the interval

[μ  -  1.5σ ,  μ + 1.5σ ]  That value is inside  μ - 2σ , μ + 2
