Exercise: A truck arrives at the scene of a fire starting from the time the fire is reported. The fire department's response time, denoted as t, is the length of time it takes for the truck to reach the scene. The response time follows a normal distribution with a mean of μ = 8.8 minutes and a standard deviation of σ = 2.5 minutes. A random sample of 32 response times is taken, and the sample mean response time, denoted as X, is computed. We want to find the mean and standard deviation of the sampling distribution of sample means (μX and σX). Additionally, we want to determine the probability that the mean response time is between two values (a and b).
