The probability that a radish seed will germinate is 0.7. A gardener plants seeds in batches of
Harlamova29_29 [7]

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

<u>Solution:</u>

<em><u>In binomial distribution, standard deviation is given as:</u></em>

\sigma=\sqrt{np(1-p)}

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

<em><u>Then, the standard deviation for the number of seeds germinating in each batch.</u></em>

Plugging in values in formula, we get

\sigma=\sqrt{(8)(0.7)(1-0.7)}\\\\=\sqrt{(8)(0.7)(0.3)}\\\\=\sqrt{1.68}\\\\=1.29614\approx1.3

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