Andre45 [30]

Answer:

Required probability is 0.9748

Step-by-step explanation:

given data

mean \mu = 117.7-cm

standard deviation \sigma = 2.2-cm

sample size n = 29

solution

we consider here random variable which represents here length of rod= x

so get here first z that is express as

Z = \dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}    

put here value with x value 118.5-cm

Z = \dfrac{118.5-117.7}{\dfrac{2.2}{\sqrt{29}}}

Z = 1.9582

p value is 0.9748

so required probability is 0.9748
