Answer 1

hello attached is the missing part of your question and the answer of the question asked

answer : 0.2951

Explanation:

Given data:

number of persons allowed in the elevator = 15

weight limit of elevator = 2500 pounds

average weight of individuals = 152 pounds

standard deviation = 26 pounds

probability that an individual selected weighs more than 166 pounds

std = 26 , number of persons(x) = 15, average weight of individuals(u) = 152 pounds

p( x > 166 ) = p( x-u / std, 166 - u/ std )

= p ( z >
`(166-152)/(26)` )

= 1 - p( z < 0.5385 )

p( x > 166 ) = 1 - 0.70488 = 0.2951
