The alternative hypothesis is
Step-by-step explanation:
Considering the first statement
Testing 100 right-handed participants on the reaction time of their left and right hands to determine if there is evidence for the claim that the right hand reacts faster than the left.
Yes, the analysis does involve a statistical test.
The null hypothesis is ,
The alternative hypothesis is
Here is the average reaction time of the right hands for the right-handed participants
and is the average reaction time of the left hands for the left-handed participants
Considering third statement
Polling 1000 people in a large community to determine if there is evidence for the claim that the percentage of people in the community living in a mobile home is greater then 10%.
The percentage of people in the community living in a mobile home is denoted with p
The sample size is n = 1000
The null hypothesis is ,
The alternative hypothesis is
Answer:
Step-by-step explanation:
The standard form of a circle is written as such:
Where (h, k) is the center of the circle, and r is the radius.
We know that the center is (-7, 0), so we can plug that into the equation like this:
The radius is 3 * the square root of 3. To square this, we can multiply 3 squared and the square root of 3 squared:
So, your standard form equation is the following:
