Uni-go company makes motorized unicycles. uni-go is deciding whether to include a safety feature that would cost $6 for each unicycle. uni-go estimates the probability of death without the safety feature is 1/90,000 and the death cost per unicycle is $5.55. if uni-go has underestimated by oneminus half the true value of a life, what is the true death cost per unicycle?

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
