b. between 10 to 12 sheets
c. more than 14 sheets.

Expert Solution
Step 1

The question is about normal distribution

Given :

Avg. no. of of leaves on apple seedlings ( μ ) = 12 sheet

Std. deviation of no. of leaves on apple seedlings ( σ ) = 2 sheet

 

To find :

a ) % of plant seeds that have at least 10 sheets

b ) % of plant seeds that have between 10 to 12 sheets

c ) % of plant seeds that have more than 14 sheets
