Answer:
The prevalence of serious defects in this population at the time of birth is 10%.
Step-by-step explanation:
The prevalence of serious defects is the number of infants that were born with seriours birth defects divided by the total number of infants born.
In this problem, we have that:
There were 1000 newborn infants.
100 infants were born with serious birth defects.
Calculate the prevalence of serious defects in this population at the time of birth.
This is:
The prevalence of serious defects in this population at the time of birth is 10%.
Answer:
120 minutes
Step-by-step explanation:
the total bill was $58 so we have to subtract the $40 monthly bill part to find how much extra money she paid because her call was over 200 minutes
58-40=18
Then divide the $18 by $0.15 since the $18 is the total amount of each time she was charged $0.15 for going 1 minute over 200 minutes
18÷0.15 = 120
120 is te Amount Of minutes she went over her 200 minute limit
Answer:
Larger for the sample of Canadians
Step-by-step explanation:
The larger the sample size, the smaller the standard deviation (sampling variability) associated with the sample means and vice-versa.
The sample of Canadians is smaller, it is expected that their sampling variability is larger than the sample of Canadians based on the rule that as the sample size increases, the standard deviation of the means decreases; and as the sample size decreases, the standard deviation of the sample means increases
Answer:
Unit Rate of Change = 1.27%
Step-by-step explanation:
In 2000, t=1 and Total Music sales = 24.8%
In 2007, t=7 and Total Music sales = 32.4%
The Slope 
The Unit Rate of Change is 1.27% and it means that the Total Music Sales Increased by approximately 1.27% every year.
