9.54 -9.55 20
9.56 -9.57 32
9.58 -9.59 22
9.60 -9.61 eight
9.62 -9.63 6
9.94 -9.95 4

obtain the expected number of bulbs from a random sample of 2000 bulbs having life.

1) more than 3000 hrs 2) ranging from 2600 and 2800 hrs

OR

(b) A certain product has been statistically controlled at a process avg. of 36.0 and a S.D. of 1.00. The product is presently being sold to 2 users who have various specification requirements. User A has established a specification of 38.0 + or - 4.0 for the product , and user B has specification of 36.0 + or - 4.0

(i) Based on the current process set up what percent of the product will not meet the specifications set up b the user A?

(ii) What percentage of the product will not meet the specifications of user B?

(iii) Assuming that the 2 users need are equal . A suggestion is made to shift the process target to 37.0 At this suggested value, what percentage of the product will not meet the specifications of user A

(iv) At the suggested process target, what percentage of the product wil not meet the specificatons of user B?

(v) Do you think that this shift to a process target of 37.0 would be desirable ? discuss your ans.
