Explanation / Answer

Solutionb:

Step 1:

Since =20 and =2 we have:

P ( X<16 )=P ( X<1620 )=P (X<16202)

Since x/=Z and 1620/2=2 we have:

P (X<16)=P (Z<2)

Step 2: Use the standard normal table to conclude that:

P (Z<2)=0.0228

ANSWER :0.0228

IF 100 FERTLIZED EGGS WERE RANDOMLY SELECTED,2 OF THEM WOULD BE EXPECTED TO HATCH IN LESS THAN 16 DAYS.

SolutionC:

Step 1:

Since =20 and =2 we have:

P ( X>24 )=P ( X>2420 )=P ( X>24202)

Since Z=x/ and 2420/2=2 we have:

P ( X>24 )=P ( Z>2 )

Step 2: Use the standard normal table to conclude that:

P (Z>2)=0.0228

ANSWER:0.0228

IF 100 FERTILIZED EGGS WERE RANDOMLY SELECTED,2 OF THEM WOULD BE EXPECTED TO TAKE MORE THAN 24 DAYS TO HATCH

SOLUTIOND:

Step 1:

Since =20 and =2 we have:

P ( 18<X<20 )=P ( 1820< X<2020 )=P ( 1820/2<X/<2020/2)

Since Z=x/ , 1820/2=1 and 2020/2=0 we have:

P ( 18<X<20 )=P ( 1<Z<0 )

Step 2: Use the standard normal table to conclude that:

P ( 1<Z<0 )=0.3413

ANSWER :0.3413
