Explanation / Answer

Solution4:

For normal distribution which is symmetrical

mean=median=mode

which is a property of normal distribution

so median=18.6

Solution5:

we have mean =median=mode for normal distribution

so mode=mean=5.8

Solution6:

mean=0.34 mm

sd=0.10 mm

P(x>0.47) to be found

z=x-mean/sd

z=0.47-0.34/0.1

=0.13

P(Z>0.13) to be found

P ( Z>0.13 )=1P ( Z<0.13 )=10.5517=0.4483

ANSWER 44.83%

Solution7:

P(X<0.50) to be found

z=0.5-0.34/0.10

z=1.6

P(z<1.6)

P ( Z<1.6 )=0.9452

From standard normal table

So answer is

94.52%
