Suppose a normal distribution has a mean of 222 and a standard deviation of
Flura [38]

Answer:

C) 53.3%

The probability that a data value is between 206 and 230

P( 206 ≤X≤230) = 0.5328 = 53.3%

Step-by-step explanation:

<u><em>Explanation</em></u>

<em>Given that Mean of the Normal distribution(μ)  = 222</em>

Given that the standard deviation of the Normal distribution (σ) = 16

Let 'X' be the random variable in the Normal distribution

<em>we have to find that the probability that a data value is between 206 and 230</em>

<u><em>solution:-</em></u>

<u><em>Step(i):-</em></u>

Let  'X' = 206

Z = \frac{x^{-}-mean }{S.D} = \frac{206-222}{16} = -1

Let X = 230

Z = \frac{x-mean }{S.D} = \frac{230-222}{16} =  0.5

<u><em>Step(ii):-</em></u>

The probability that a data value is between 206 and 230

P( 206 ≤X≤230) = P( -1≤Z≤0.5)

                          = |A(0.5)+A(-1)|

                         = 0.1915+0.3413

                         = 0.5328

<u><em>final answer:-</em></u>

<em>The probability that a data value is between 206 and 230</em>

<em>P( 206 ≤X≤230) = 0.5328 = 53.3%</em>
