6 0

Answer:

0.9726

Explanation:

The computation of the probability of a sample mean is shown below:

P(\bar x < 24.3)

To find the probability first we have to determine the z score which is

z = \frac{\bar x - \mu_{\bar x}}{\sigma_{\bar x}} \\\\ = \frac{\bar x - \mu }{\frac{\sigma}{\sqrt{n} } } \\\\ = \frac{24.3 - 24}{\frac{1.25}{\sqrt{64} } }

= 1.92

Now probability is

P(\bar x < 24.3) \\\\= P(z < 1.92)

= 0.9726

Hence, the probability of the sample mean is 0.9726

We simply applied the above formulas to determined the probability of a sample mean and the same is to be considered

The technique that is known to be  illustrated is said to be DNA hybridization.

<h3>What is  DNA hybridization?</h3>

In the study of genome, DNA hybridization is known to be a kind of a molecular biology method that is often used to know the measures or the degree of genetic similarity that exist between a given pools of DNA sequences.

DNA hybridization is also seen as ability of two  given strand of complementary DNA that tends to pair with another strand and it is one that  can be used to find out other similar DNA sequences in two other kinds of species or within a given genome of a single species.

Note that in the case above, The technique that is known to be  illustrated is said to be DNA hybridization.
