Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a variance of 2,250,000 and a mean
Svet_ta [14]

Answer: 0.1357

Step-by-step explanation:

Given : Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a variance of \sigma^2=2,250,000 and a mean life span of \mu=13,000 hours.

Here , \sigma=\sqrt{2250000}=1500

Let x represents  the life span of a monitor.

Then , the probability that the life span of the monitor will be more than 14,650 hours will be :-

P(x>14650)=P(\dfrac{x-\mu}{\sigma}>\dfrac{14650-13000}{1500})\\\\=P(z>1.1)=1-P(z\leq1.1)\ \ [\because\ P(Z>z)=1-P(Z\leq z)]\\\\=1-0.8643339=0.1356661\approx0.1357

Hence, the probability that the life span of the monitor will be more than 14,650 hours = 0.1357
