Answer:
75 plants will be taller
Step-by-step explanation:
Given mean = 64 and standard deviation = 3.5
To get normal curve , we find one , two and three standard deviation from the mean.
To get one standard deviation we add and subtract 3.5 from mean
-1 SD =60.5 , +1 SD = 67.5
-2 SD =57 , +2 SD = 71
-3 SD = 53.5 , +3 SD = 74.5
The graph is attached below with percentages
(b) from the graph we can see that, 2.5% are after 71
that means 2.5% plants are taller than 71 inches
3000* 2.5% = 3000*0.025 = 75
75 plants will be taller
