Answer:

Probability = 0.943

Step-by-step explanation:

15.6% = 0.156(probability of handwritten records with missing data)

X = random variable denoting number of handwritten records whose data are missing

Values of x = 0,1...10

Using the binomial distribution

X~binomial (10,0.156)

P(x<=3)

P(x= 0)+p(x=1)+...+p(x=3)

10C0(0.156)⁰(1-0.156)¹⁰+10C1(0.156)¹(1-0.156)⁹+10C2(0.156)²(1-0.156)⁸+10C3(0.156)³(1-0.156)⁷

This gives a probability of 0.943.

g(x) = 1/2x - 11

g(x) = -5

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute:                    -5 = 1/2x - 11
  2. Isolate <em>x</em> term:              6 = 1/2x
  3. Isolate <em>x</em>:                       12 = x
  4. Rewrite:                        x = 12
