Answer:
Option A is right
Step-by-step explanation:
Given that approximately 52% of all recent births were boys. In a simple random sample of 100 recent births, 49 were boys and 51 were girls. The most likely explanation for the difference between the observed results and the expected results in this case is
A) variability due to sampling
-- True because there is a slight difference whichmay be due to sampling fluctuations.
B) bias
False because given that 100 random births selected
C) nonsampling error
False. There is no chance for systematic error here.
d) Confounding: There is no confounding variable present inchild birth since each is independent of the other
e) a sampling frame that is incomplete
False because the sampling is done correctly.
Answer:
x=4.2
Step-by-step explanation:
7.8x = 32.76
/7.8 /7.8
x=4.2
Answer:
A. 0.083%
Step-by-step explanation:
Total population=60,000
Total infected=600
Percentage of total infected=600/60,000×100
=0.01×100
=1% of the total population
50 people died out of total infected
Percentage of death of total infected=50/600×100
=8.33%
Total death from all causes=110
Percentage of total death from all causes to the total population=110/60,000×100
=0.1833%
Proportionate mortality rate(PMR) of dengue in the population can be calculated as:
Percentage of death from total infected to the total population
=50/60,000×100
=0.0833%
Approximately 0.083%
