Answer:
5
Step-by-step explanation:
Add the numbers together, then divide that by the amount of numbers
(2 + 7 + 6 + 1 + 9 + 2 + 4 + 9)/8
40/8 = 5
Answer:
Based on the 95% confidence interval for the difference in population proportion, there is convincing statistical evidence that he is correct
Step-by-step explanation:
The proportion from the sample of people from his party that support the law = 70%
The number the members of the politicians political party that support the law = 550 people
The proportion from the sample of people from the other party that support the law = 65%
The number the members of the politicians political party that support the law = 420 people
The confidence level of the test = 95%
The given confidence interval for the difference in proportion, C.I. = (-0.010, 0.110)
Given that the 95% confidence interval for the difference in population proportion ranges from -0.010, to 0.110, it is 95% certain that 0 is among the likely difference in proportion between the two populations and therefore, there is sufficient statistical evidence to suggest that there is no difference in the proportion of the members of either political that support the proposed new traffic law.
Given:
Total number of problems = 24
Michael completed
of his homework in
of an hour.
To find:
What fraction of his homework would he complete in one hour.
Solution:
We have,
Part of work done in
of an hour 
Part of work done in an hour 

Therefore, he complete
of his homework in 1 hour. Hence, all options are incorrect.
I believe Hector is correct
