The probability that a randomly selected person with a kidney stone will take longer than 16 days to pass it is 0.15866 , the minimum number for the upper quarter of the time to pass a kidney stone days is 14.4 .
<h3>What is Probability ?</h3>Probability is the measure of likeliness of an event to happen
Let X denote the time to pass the kidney stone.
The random variable X follows normal Distribution
mean = 12 days days
standard deviation = 4 days
The distribution of X is X - N ( 12 , 4)
The probability that a randomly selected person with a kidney stone will take longer than 16 days to pass it is
P ( X > 16) = 1 - P( X ≤ 16)
= 1 - P( Z ≤ (16-12)/4)
= 1 - P ( Z ≤ 1 )
= 1 - 0.84134
= 0.15866
P( X < x₀) = 0.75
Using the excel function the z score for the area 0.75 is
z - score = 0.6745
x₀ = 0.6 * 4 + 12
x₀ = 14.4

Step-by-step explanation:
Let be the average number of hours a person drive without adding the product.
Given claim : An infomercial claims that a woman drove 33 hours without oil.
i.e.
It is known that the null hypothesis always contains equal sign and alternative hypothesis is just opposite of the null hypothesis.
Thus the null and alternative hypothesis for the given situation will be :-
