Here is the full question:
Answer:
(a) 0.2007
(b) 0.2510
(c) 0.2150
Step-by-step explanation:
Given that:
The sample size = 10
Sample proportion= 60% 0.6
Let X represents the no of streaked-shell snails.
The Probability mass function (X) is:
The Binomial probability with mean μ = np
= 10 * 0.6
= 6
Standard deviation σ =
=
= 1.55
The probability that the percentage of the streaked-shelled snails in the sample will be:
a)
= 0.2007
b)
= 0.2510
c)
= 0.2150
