Complete Question

The complete qustion is shown on the first uploaded image

Answer:

The correct option is B

Step-by-step explanation:

From the question we are told that

      The sample size  is  n = 49

       The mean is  \mu  =  17ppb

       The standard deviation is \sigma =  14 ppb

Generally the standard error of this measurement is mathematically represented as

       \sigma_z  =  \frac{\sigma}{\sqrt{n} }      

substituting values

      \sigma_{\= x}  =  \frac{14}{\sqrt{49} }  

     \sigma_{\= x}  =  2ppb

Now the probability that the mean lead level from the sample of 49 measurements T is less than 15 ppb represented as P(X < 15 )

Next is to find the z value

    z =  \frac{\mu -\sigma }{\sigma_{\= x}}

     z =  \frac{15-17}{2}

      z =  -1

Now checking the z-table for the z-score of  -1 we have  

      P(X

Least to greatest, the triples are (2x, x²-1, x²+1). Thus the value in the first column of the table is half the value of the first of the triples. Your completed table will be

\begin{array}{cc}\text{x-value}&\text{triple}\\3&\bf{(6,8,10)}\\\bf{4}&(8,15,17)\\5&\bf{(10,24,26)}\\\bf{6}&(12,35,36)\end{array}
