he life of Philips voice recorder is normally distributed with a mean of 4.1 years and a standard deviation of 1.3 years. A voice recorder is guaranteed for 3 years. We are interested in the length of time a voice recorder lasts. Find the probability that a voice recorder will break down during the guarantee period. P(0 < χ < ["", ""] ) = ["", ""] (Use zero (0) for the minimum value of x.) Find the probability that a voice recorder will last between 2.8 and 6 years. P( ["", "", ""] < χ < ["", "", ""] ) = ["", "", ""] Find the 70th percentile of the distribution for the time a voice recorder lasts. P(χ < ƙ)= ["", ""] . Therefore, ƙ= ["", ""]

P(0 < χ < ["", ""] ) = ["", ""] (Use zero (0) for the minimum value of x.)
Find the probability that a voice recorder will last between 2.8 and 6 years.
P( ["", "", ""] < χ < ["", "", ""] ) = ["", "", ""]
Find the 70th percentile of the distribution for the time a voice recorder lasts.
P(χ < ƙ)= ["", ""] . Therefore, ƙ= ["", ""]
