Two statements are given followed by two conclusions as responses. You have to consider the statements to be true even if they seem to be at variance from the commonly known facts. You have to decide which of the given conclusion(s) can definitely be drawn from the given statements. Statements: The recent trend towards enjoying songs that have raps has led to only these songs topping the charts.

Conclusions: The song which is currently topping the charts is about a taboo subject. II.The song which is currently topping the charts does not have a rap.

A

Only Conclusion I follows.

B

Only Conclusion II follows.

C

Both the Conclusions I and II follow.

D

Neither Conclusion I nor II follows.

Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.

A

Both statements I and II

B

Both statements II and III

C

Both statements I and III

D

All of the above

False

Shewhart control charts are better for phase II applications than the Cusum charts.

A

True

B

False

Which of these is a reason, why the Cusum charts are better than the Shewhart control charts?

A

Because they are having information about only one sample

B

Because the quantity plotted on the Shewhart control charts is variable

C

Because the quantity plotted on the Cusum chart contains information about more than one sample

D

Because the quantity plotted on the Cusum control charts is containing information about a single sample
