C. 71%
It is really .708 but just round it up to .71.
Answer:
c. 106 million
Step-by-step explanation:
A = number of people in the sample that use public transportation 5 or more days per week
A = 2,067,153
B = number of people total in the sample
B = 4,295,280
C = proportion of those in the sample that use public transportation 5 or more days per week
C = A/B
C = (2,067,153)/(4,295,280)
C = 0.48126 approximately
Multiply this value by the figure 220 million to compute the estimated number of people who use public transportation 5 or more days per week
C*(220 million) = 0.48126*(220 million) = (0.48126*220) million = 105.8772 million = 106 million
Answer:
For a bilateral test the p value would be:
Step-by-step explanation:
Information given
n=225 represent the sample selected
X=87 represent the households with incomes below the poverty level
estimated proportion of households with incomes below the poverty level
is the value that we want to test
z would represent the statistic
represent the p value
System of hypothesis
We want to check if the true proportion is equal to 0.32 or not.:
Null hypothesis:
Alternative hypothesis:
The statistic is given bY:
(1)
Replacing we got:
For a bilateral test the p value would be:
Assuming that this question is based on a graph, and that this graph tells us that people 50-64 years make up 35% of all the voters, then it would mean that
35%of 12000=

So, assuming that people at age 50-64 make up 35% of the voters, then 4200 of them voted.
