Keeping car tires inflated is essential to safe driving. For one type of car tire, the tire pressure in pounds per square inch (psi) is assumed to be approximately Normal with a mean of 35 psi and a standard deviation of 2 psi. A tire is labeled as underinflated if its pressure is 32 psi or below. What percentage of tires are underinflated?

a. 2.28%
b. 6.68%
c. 93.32%
d. 97.72%​

Answer:

B 6.68

Step-by-step explanation:

The solution is, 30.854% is the percentage of tires are underinflated.

In statistics, the standard score is the number of standard deviations by which the value of a raw score is above or below the mean value of what is being observed or measured. Raw scores above the mean have positive standard scores, while those below the mean have negative standard scores.

here, we have,

First, we find the z-score corresponding to the value given

z-score = (x - mean)/SD

Z-score = (36-35)/2 = 1/2 = 0.5

we find the Probability of (x > 0.5)

we use the standard normal distribution table for this

P( x > 0.5) = 0.30854

This has a percentage 30.854%.
