Answer:
Now we can find the p value with the following probability:
Step-by-step explanation:
Information given
n=97 represent the random sample taken
estimated proportion of defective
is the value to verify
z would represent the statistic
represent the p value
Hypothesis to tests
We want to tet if the true proportion is less than 6%, the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
Now we can find the p value with the following probability:
To find this, we have to multiply the total amount of gas the tank can hold (40 gallons) by how much gas is in the tank (93.5% or .935 as a decimal). When we do this we get the amount of gas 37.4 gallons.
