The probability that a radish seed will germinate is 0.7. a gardener plants seeds in batches of
8. find the standard deviation for the number of seeds germinating in each batch.
o 1.7
o2.8
01.3
o 16.8

The standard deviation for the number of seeds germinating in each batch is 1.3

Solution:

In binomial distribution, standard deviation is given as:

Where "n" is the number of observations

"p" is probability of getting success

We are given that:

Total batches of seed = 8

Probability that a radish seed will germinate is 0.7

Here success is getting radish seed germinated

Then, the standard deviation for the number of seeds germinating in each batch.

Plugging in values in formula, we get

Therefore the standard deviation for the number of seeds germinating in each batch is 1.3

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
