Let X = hourly median power (in decibels) of received radio signals transmitted between two cities. It is believed that the lognormal distributionprovides a reasonable probability model for X. If the parameter values are u = 3.5 and o = 1.2, calculate the probability that received power is morethan 200 dB.Excel Worksheet-1.xlsx Click to open:O 0670O .9330O 1.4986O .2069O something else

Components that are critical for the operation of electrical systems are replaced immediately upon failure. Suppose that the life time of a certain such component can be modeled by a lognormal distribution with mean u = 500 hours and standard deviation o = 100 hours. Find the median life time of the components. (Use four digits after the decimal point, e.g. 0.1234) Hint: You need to start by finding the values of 0 and w?. Type your answer..
Terri Vogel, an amateur motorcycle racer, averages 129.52 seconds per 2.5 mile lap (in a 7 lap race) with a standard deviation of 2.28 seconds .

An article in a magazine discussed the length of time till failure of a particular product. At the end of the product's lifetime, the time till failure is modeled using an exponential distribution with a mean of 500 thousand hours. In reliability jargon this is known as the "wear-out" distribution for the product. During its normal (useful) life, assume the product's time till failure is uniformly distributed over the range 200 thousand to 1 million hours. Complete parts a through c. a. At the end of the product's lifetime, find the probability that the product fails before 600 thousand hours. (Round to four decimal places as needed.)

Previously, De Anza's statistics students estimated that the amount of change daytime statistics students carry is exponentially distributed with a mean of $0.88. Suppose that we randomly pick 25 daytime statistics students. Find the probability that an individual had between $0.80 and $1.00. Graph the situation, and shade in the area to be determined.
Two geysers that are near to each other are labelled as Geyser A and Geyser B. The time between eruptions for a given geyser follows an exponential distribution. The eruption times of the two geysers are independent of one another. The mean amount of time between eruptions of Geyser A is 39 minutes, and the mean amount of time between eruptions of Geyser B is 66 minutes. Given that exactly one of the geysers erupts within the next 49 minutes, determine the probability that it will be Geyser A. O 0.6654 0.7850 O 0.7252 O 0.6953 O 0.7551
