Which statement best describes the data set?

zhannawk [14.2K]

Answer:

It is neither accurate nor precise.

Explanation:

The data set is neither accurate nor precise.

Accuracy is defined as the closeness of a measurement to the true value.

Now let us look at the average of the data set:

30 + 17 + 27 + 21 + 32 = 127/5 = 25.4

The average of the data set is 25.4, whereas the correct value provided is 25. The difference between the average of the data set and the correct value is 0.4 which is beyond the margin of error allowed in measurement. Hence, the measured data is not accurate.

Also, precision is defined as the closeness of repeated measurement to one another.

From the data set, the individual values are not close to one another in any form and the difference between them are more than the margin of error allowed in measurements. Hence, the data is far from being precise.

If two intermediate-colored chickens together produced 100 chicks, how many would you expect to be black?

sergiy2304 [10]

Answer: 25 of the chicks will be black

Explanation: Since the chickens are intermediate in colour, that is they are not black, they are heterozygous. Let B represent the allele for black colour and B represent the allele for blue colour, therefore the genotype of a chicken with an intermediate colour is Bb. A cross between two Bb chicken will produce 1 BB, 2 Bb and 1 bb chicks. 1 BB will manifest outwardly as black, 2Bb will manifest outwardly as intermediate colored while 1 bb will manifest outwardly as blue colored chicks.

Since one out of four chicks are black colored, if the two chicken produced 100 chicks, the number of chicks that will be black is 1/4 x 100 = 25. Therefore, 25 chicks out of 100 will be black.
