processes into the ready queue‚ the average waiting time and turn around time can be calculated by using the above algorithm. ALGORITHM: 1) start 2) read the no of processes to n 3) initialize i to 0 4) if ia[j] then a) swap a[i] and a[j] b) swap at[i] and at[j] c) swap b[i] and b[j] 8) from i=0 to n do a) w[i]=s-b[i]-at[i] b) s=s+a[i] c) avg=avg+w[i] 9)tt=tt+avg 10) tt=tt/n 11) avg=avg/n 12)write the turn around time and average waiting time 13) stop 2) AIM: To write a program

poets who use love as the subject of several of her poems. In "if you were coming in the fall‚" Emily Dickinson uses several metaphors to enhance the theme of the time spent waiting for love.

I feel that it is important to educate people on organ donation because first‚ we don ’t have enough donors and second‚ because we can never have too many

1. An article in Marketing News argued that the level of significance used when comparing two products is often too low – that is‚ sometimes you should be using an α value greater than 0.05. Specifically‚ the article recounted testing the proportion of potential customers with a preference for product 1 over product 2. The null hypothesis was that the population proportion of potential customers preferring product 1 was 0.50 and the alternative hypothesis was that it was not equal to 0.50. the p-value
