Assume that speeds on a given road are normally distributed with a mean speed of 35 mph and a standard deviation of 5 mph. Find the 98th percentile speed (thespeed at or below which 98% of the traffic moves).Click here for page 1 of the Areas under the Normal Curve TableClick here for page 2 of the Areas under the Normal Curve Table......The 98th percentile speed is mph. (Round to the nearest integer as needed.)

Solution-: Let, X= The speed on a given road Given: μ=35mph,σ=5mph ∴X→ N(μ=35,σ2=52) We find 98th…

Answered: Assume that speeds on a given road are…
