A certain type of seed has a 75 % germination rate. You plant 20 or these seeds in your garden. Let the random variable X be the number of seeds that germinate out of the 20. a) Find the mean m for the random variable. m = Blank 1. Fill in the blank, read surrounding text. b) Find the standard deviation s for the random variable. Give to 2 decimal places. s = Blank 2. Fill in the blank, read surrounding text. c) Find the probability that exactly 15 seeds germinate, that is, find P(X = 15). Give the final answer as a decimal rounded to 4 decimal places. P(X = 15) = Blank 3. Fill in the blank, read surrounding text.

a) Find the
m = Blank 1. Fill in the blank, read surrounding text.
b) Find the standard deviation s for the random variable. Give to 2 decimal places.
s = Blank 2. Fill in the blank, read surrounding text.
c) Find the probability that exactly 15 seeds germinate, that is, find P(X = 15).
Give the final answer as a decimal rounded to 4 decimal places.
P(X = 15) = Blank 3. Fill in the blank, read surrounding text.
d) Find the probability that at most 15 seeds germinate, that is, find P(X ≤ 15).
Give the final answer as a decimal rounded to 4 decimal places.
P(X ≤ 15) = Blank 4. Fill in the blank, read surrounding text.
e) Find the probability that at least 15 seeds germinate, that is, find P(X ≥ 15).
Give the final answer as a decimal rounded to 4 decimal places.
P(X ≥ 15) = Blank 5. Fill in the blank, read surrounding text.
