QUESTION 25Suppose the age of cars on the road is normally distributed with a mean of 9.4 years. If the standard deviation is known tobe 2.2 years, what is the probability that 16 randomly selected cars have been on the road between 7 and 8 years? Roundyour answer to four decimal places.

Solution-: Given: μ=9.4,σ=2.2,n=16 Let, X= The age of cars on the road ∴X→ N(μ=9.4,σ2=2.22) We want…
