Answer:
Position of point X on the number line must be X = -27
Step-by-step explanation:
Notice that there are 14 units between W and Y, since the absolute value of their difference is :
| -15-(-29) | = | -15 + 29 | = 14
Now let's write an equation that tells as what is the distance between W and X in terms of WY knowing that we want WX to be 1/7 of WY:
This is telling us that the point X must be located two (2) units to the right of point W. That is W + 2 = -29 + 2 = -27
Position of point X on the number line must be X = -27
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:
