According to an NRF survey conducted by BIGresearch, the average family spends about $237 on electronics (computers, cell phones, etc.) in back-to-college spending per student. Suppose back-to-college family spending on electronics is normally distributed with a standard deviation of $54. If a family of a returning college student is randomly selected, what is the probability that: (a) They spend less than $135 on back-to-college electronics? (b) They spend more than $370 on back-to-college electronics? (c) They spend between $135 and $185 on back-to-college electronics? (Round the values of z to 2 decimal places. Round your answers to 4 decimal places.) (a) P(x < 135) = enter the probability that they spend less than $135 on back-to-college electronics (b) P(x > 370) = enter the probability that they spend more than $370 on back-to-college electronics (c) P(135 < x < 185) = enter the probability that they spend between $135 and $185 on back-to-college electronics

Question
According to an NRF survey conducted by BIGresearch, the average family spends about $237 on electronics (computers, cell phones, etc.) in back-to-college spending per student. Suppose back-to-college family spending on electronics is
(a) They spend less than $135 on back-to-college electronics?
(b) They spend more than $370 on back-to-college electronics?
(c) They spend between $135 and $185 on back-to-college electronics?
(Round the values of z to 2 decimal places. Round your answers to 4 decimal places.)
(a) P(x < 135) = enter the probability that they spend less than $135 on back-to-college electronics (b) P(x > 370) = enter the probability that they spend more than $370 on back-to-college electronics (c) P(135 < x < 185) = enter the probability that they spend between $135 and $185 on back-to-college electronics |
