Answer:

They do not form a proportion

Step-by-step explanation:

20/1 does not equal to 10/100

20/1 = 20

10/100 = 1/10

The 2 are not equal, so it does not form a proportion.

The probability distribution for the number of defects in a shipment of alarm clocks, based on past data, is given below. Find t
Kay [80]

Answer:

0.29

Step-by-step explanation:

Given :

n : ___ 0 _____ 1 ____ 2 ____ 3 ____ 4

P(n) : 0.82___ 0.11 ___0.04 _0.02 ___0.01

The expected number of defect in a shipment can be obtained using the expected value formula :

Expected value, E(X) = Σx*p(x)

Σx*p(x) = (0*0.82) + (1*0.11) + (2*0.04) + (3*0.02) + (4*0.01)

E(X) = 0.29

Hence, the expected number of defect in shipment is 0.29
