Roll No .
1- Statistical survey is known as a scientific procedure for collection and analysis of numerical data used to accumulate information about products. Questionnair and schedule are both methods of collecting data in statistical review. At questionnair the queries is sent by mail to participants to fill it and send it in return. At schedule the queries is filled by enumerator. Questionnair is a more affordable process than schedule in order to was in a large samples or population. Questionnair should be stuffed by litrate and supportive but scheduke is filled enumurator. Risk of disbelief of quwstions in questionnair is more than schedule.
2- Data rendering of relatives expenditure applying Pie Graph
Back button = X1*n1 + X2*n2
where By = Merged arithmetic indicate = 10. 9
X1 = math mean of sample (1) = twelve. 4 and n1 sama dengan No . of sample (1) = 75 X2 sama dengan arithmetic mean of test (1) =? and n1 = Number of test (2) sama dengan 150
So… 10. on the lookout for = 10. 4 2. 100 & X2 5. 150
100 + a hundred and fifty
2725 = 1040 + X2 * 150 1685 = X2 5. 150
X2 = eleven. 23
And so the average weight of screws of field B sama dengan 11. 3
4- (a) As a decision maker oftentimes you have to act about implementing, producing or manufacturing either of one or two or some moments more span of actions. With the help of rules of probability you possibly can make the right decision of which you can implement. In case there is one of situations to be implemented the Addition rule is utilized and claims: If ‘A' and ‘B' are any kind of two incidents then the probability of the incident of both ‘A' or ‘B' has by: P(A ∪ B) = P(A) + P(B) - P(A ∩ B) If ‘A' and ‘B' are two mutually exclusive situations then the likelihood of event of whether or N is given simply by: P(A ∪ B) sama dengan P(A) & P(B)
If A, M and C are any three events then the possibility of incident of whether or M or C is...
