The probability that a radish seed will germinate is 0.7. a gardener plants seeds in batches of 11. find the standard deviation
for the random variable x, the number of seeds germinating in each batch.
1 answer:
To calculate for the standard deviation given the
probability, we use the formula:
s = sqrt (n p q)
where s is standard deviation, n is number of samples = 11,
p is probability of success = 0.7, q = 1 – p = 0.30
s = sqrt (11 * 0.7 * 0.3)
<span>s = 1.52</span>
