Answer:
Step-by-step explanation:
Information given
represent the sample mean for the content of active ingredient
represent the sample standard deviation for the sample
sample size
represent the value that we want to test
t would represent the statistic
represent the p value for the test
System of hypothesis
We need to conduct a hypothesis in order to check if the true mean for the active agent is at least 20 mg, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic would be:
(1)
Now we can calculate the statistic:
P value
The degrees of freedom are calculated like this:
Since is a one left tailed test the p value would be:
The answer is -2 when you simplify
Answer:
the value of x in this image is 38
Step-by-step explanation:
we know that the total angles of triangles are 180, so m is 180-84=96, and 180-134=46, when added we get 142, which means the last angle is 38
Answer:
Collision coverage pays for damage to your car resulting from a collision with another car, an object, such as a tree or telephone pole, or as a result of flipping over (note that collisions with deer are covered under comprehensive). It also covers damage caused by potholes.
Hope this helped. :)
