Answer:
For this case we want to test if in a certain city in the U.S. are different from the proportion of the general population of young adults in the U.S 0.16 (alternative hypothesis) and the best system of hypothesis are:
Null hypothesis: 
Alternative hypothesis:
Step-by-step explanation:
Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
Solution to the problem
For this case we want to test if in a certain city in the U.S. are different from the proportion of the general population of young adults in the U.S 0.16 (alternative hypothesis) and the best system of hypothesis are:
Null hypothesis: 
Alternative hypothesis:
Disjoint probability or mutually exclusive are alike. In terms of Venn diagram the 2 diagrams do not intersect
Answer:
It is a graph that is not a straight line - it can be described as an equation such as y =mx + c

Answer:
D. 980.2 cm
Step-by-step explanation:
Surface area of cylinder = 2¶r2 + 2¶rl
r = radius
l = lenght
¶ = 3.142
S. A = (2X3.142X6^2) + (2X3.142X6X20)
= 226.224 + 754.08 = 980.3cm2
with the more expensive light bulbs, the cost would be $155.52
with the less expensive light bulb, the cost would be $119.04
This means you would save $36.48
