Answer:
Null hypothesis:
Alternative hypothesis:
Alternatively we can express the system of hypothesis like this:
Null hypothesis:
Alternative hypothesis:
And the most reasonable choice for the options given it seems
C. H0: p = 0.004
H1: p > 0.004
Because in the null hypothesis we always need to have an equal sign and the optiosns A, B and D are not satisfying this condition
Step-by-step explanation:
For this test we are trying to test the following claim "the proportion of Americans that have seen a UFO, p, is less than 4 in every one thousand" and that would represent the alternative hypothesis. And by the complement rule we will have the null hypothesis.
Based on this the system of hypothesis for this case are:
Null hypothesis:
Alternative hypothesis:
Alternatively we can express the system of hypothesis like this:
Null hypothesis:
Alternative hypothesis:

C. H0: p = 0.004
H1: p > 0.004

It would be D because you can't have two of the same X factors with different Y outputs

Answer:
1. The distances are accurate.
2. 57 miles
Step-by-step explanation:
<u>Quiz 1 solution</u>
1 mile = 1.60934 km
10 miles will be;
10 × 1.60934 = 16.0934 km
Distance on the sign is 16 km.
The distance is accurate since 16.0934 km rounded up to nearest kilometre is equal to 16 km.
13 miles will be;
13 × 1.60934 = 20.92142 km
The distance on the sign is 21 km
This distance is accurate since 20.92142 km rounded up to nearest kilometre equals 21 km
55 miles will be;
55 × 1.60934 = 88.5137 km
The distance on the sign is 89 km
The distance is accurate since 88.5137 km rounded up to nearest kilometre is 89 km.
<u>Quiz 2 solution</u>
1 km = 0.621371 miles
92 km will be;
92 × 0.621371 = 57.166132 miles
Rounding up the answer to nearest mile gives 57 miles.
Answer:
Step-by-step explanation:
To better understand the question we need to properly format the expression
as we can see we have three brackets, we can proceed by first opening the first two brackets, we have.
we then continue by collecting like terms
we then solve for the remaining two brackets
we then continue by collecting like terms
from the two brackets we obtained each, we now have to multiply both terms together and solve we have
collecting and summing all like terms we have
