Answer:
a) To earn C he needs at least 68 and less than 98
b) No, he couldn't make it.
Step-by-step explanation:
I. His avg value is (382 + x)/6
I pick a random number and that gave
(68 => to reach 75) and (98 => to reach 80)
So that makes he needs at least 68 and less than 98
II. The reason why he cannot make it is
if 100 is 100%
= (100 + 382)/6
= 80.33 That's impossible to reach 90
Hope that help :)

The probability that the specimen's life time is more than 300 is


= 0.0992
b)The probability of the specimen's lifetime is between 100 and 250

c) The value such that exactly 50% of all specimens have lifetimes exceeding that value is

x = 192.07
