Answer to question# 22)

Event rates can be related to Chicago cubs winning, as that can be considered as an event

Event rates are not commonly used that is correct , and they do let us know how often an event occurs

The formual for event rates = number of times the event occurs out of total trials

Hence only statement d is incorrect here

.

Answer to question# 23)

Yes it is true that data collection is done to test hypothesis can it can be on one sample or more number of people

Hence only statement c is not correct here, the outcomes are called results for both the experimental group and the control group

Hence only statement c is incorrect

.

Answer to question# 24)

Age-adjusted rates can be used for all types of populations hence statement a is not true

Event rates are surely important in public health hence statement b is also not true

Person time is also used in work or labor related problems hence statement d is also not true

Yes, count data is something important when considering data gathered on vampires

Hence only statement d is true
