Assume the random variable x is normally distributed with mean p= 80 and standard deviation o = 4. Find the indicated probabilit
taurus [48]

This question is incomplete, the complete question is;

Assume the random variable x is normally distributed with mean p = 80 and standard deviation σ = 4.

Find the indicated probability.  P(67 < x < 72)

(Round to four decimal places as needed.)

Answer:

the indicated is 0.0222

Step-by-step explanation:

Given the data in the question;

mean μ = 80

standard deviation σ = 4

p ⇒ P ( x -μ  / σ )

so

P(67 < x < 72) ⇒ P( 67-80 / 4 ) < P( x -μ  / σ )  < P( 72-80 / 4 )

P(67 < x < 72) ⇒ P( -13 / 4 ) < P( x -μ  / σ ) < P( -8 / 4 )

P(67 < x < 72) ⇒ P( -13 / 4  < z < -8 / 4 )

P(67 < x < 72) ⇒ P( -3.25  < z < -2 )

⇒ P( z < -2 ) - P( z < -3.25)

Now from z table;

⇒ 0.02275 - 0.00058

P(67 < x < 72) ⇒ 0.02217 ≈ 0.0222  { four decimal places }

Therefore, the indicated is 0.0222

Rewrite 3x + 4y = 10 using function notation.
Komok [63]
If you would like to rewrite 3 * x + 4 * y = 10 using function notation, you can do this using the following steps:

3 * x + 4 * y = 10
4 * y = 10 - 3 * x      /4
y = 10/4 - 3/4 * x
y = 5/2 - 3/4 * x

The correct result would be y = 5/2 - 3/4 * x.

Type the correct answer in each box. Spell all words correctly, and use numerals instead of words for numbers. If necessary, use
S_A_V [24]

Mean = 3.25

Solution:

Step 1 : Given data:

4.5, 3, 1, 2, 4, 3, 6, 4.5, 4, 5, 2, 1, 3, 4, 3, 2

Step 2:

Sum of the numbers

          = 4.5 + 3 + 1 + 2 + 4 + 3 + 6 + 4.5 + 4 + 5 + 2 + 1 + 3 + 4 + 3 + 2

          = 52

Sum of the numbers = 52

Number of terms = 16

Step 3:

$\text{Mean}=\frac{\text{Sum of the numbers}}{\text{Number of terms}}

         $=\frac{52}{16}

         = 3.25

Mean = 3.25

Mean of the distribution is 3.25.
