Question Find the probability that a randomly selected portable MP3 player from Company XYZ will have a replacement time less than 1.2 years, given the replacement times are normally distributed with μ=3.7\mu=3.7 years and σ=1\sigma=1 year.

Studdy Solution
Report the probability accurate to 4 decimal places:
P(X<1.2 years )=P(Z<2.5)0.0062 P(X < 1.2 \text{ years }) = P(Z < -2.5) \approx 0.0062
The probability that a randomly selected portable MP3 player will have a replacement time less than 1.2 years is approximately 0.0062.
