A probability distribution on the real line is a mixture of two classes +1 and−1 with density N(1,2) (normal distribution with mean1 and variance 2) andN(3,1), with prior probabilities (probability of eachclass) 0.4 and 0.6 respectively. What is the Bayes decision rule? Give anestimate for the Bayes risk.

Travel at the speeds of 65 miles per hour to drive the distance of 310 miles (if the speed in which the person in question is traveling at the same speed) =
310 divided by 65 =
= 4 and
hours
since it is "traveled distance = speed multiplied by time it takes
310 divided by 65 =
= 4 and
since it is "traveled distance = speed multiplied by time it takes
The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.
<h3>Z score</h3>Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
Where x is raw score, μ is mean, σ is standard deviation
Given that:
σ = 4, μ = 56, hence
for x = 62:
for x = 47:
for x = 56:
The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.
