Answer:
The probability for the proportion of apples with diameters less than 3.5 inches is 0.1056.
Explanation:
For a normal distribution, z score is calculated using this formula: (X-μ)/σx
Where Mean, μ = 4
Standard deviation, σ = 0.400
The probability for the proportion of apples with diameters less than 3.5 inches is expressed below:
Probability = P(X<3.5)
= P(Z<-1.25)
Probability = 0.1056
