1 dozen = 12
12 x 2 = 24
8/3 = x/24
3x=192
x=64
two dozen socks would cost $64
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:
Ask some people if they got buses and tell them y
You have to place the numbers on the correct location of the number line. Let me guide you ☺
0.5 goes halfway between the 0 and 1. You will place a dot which is called a point halfway between 0 and 1.
-2.1 going to the left you will place a tiny dot that represents -2.10.
1 2/3 also known as 1.66 will be placed beteeen the 1 and 2. I think you are getting the picture now. right!
