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