Answer: hello your question is incomplete below is the missing part
Determine the proportion of radishes grown without fertilizers with weight less than 50grams
answer : p( x < 50 ) = 0.84
Step-by-step explanation:
Radish grown in without fertilizers ( normally distributed )
mean = 40 g
standard deviation = 10 g
Radish grown with fertilizers ( normally distributed )
Mean = 140 g
standard deviation = 40 g
<u>Determine the proportion of radishes grown without fertilizers with weight less than 50 grams </u>
lets assume x = radish without fertilizers
y = radish with fertilizers
hence
p( x < 50 ) = P ( (x-μ / б) < )
= p ( z < 1 ) = 0.5 + p ( 0 < z < 1 )
p( x < 50 ) = 0.5 + 0.3413 = 0.8413
attached below is the distribution related to this solution
