I can't understand your question

Answer 2

Answer:

here ,

n = 0.60

half test means 50 question

Formula: Reliability coefficient (rn)= nr/1+(n-1)r

rn = new reliability coefficient

r = old reliability coefficient

n = ratio of new and old no. of items = 100/50 = 2

Step-by-step explanation:

rn = nr/ 1+(n-1)r

rn = 2 × 0.60 / 1 + ( 2-1)0.60

rn = 1.2 / 1 + (1 × 0.60 )

rn = 1.2 / 1 + 0.60

rn = 1.2 / 1.6

rn = 0.75
