7.3 Central Limit Theorem: Finding Probability A population of values has a normal distribution with $\mu = 151.4$ and $\sigma = 26$. You intend to draw a random sample of size $n = 55$. Find the probability that a sample of size $n = 55$ is randomly selected with a mean less than 145.8. $P(M < 145.8) =$ (Round to 4 decimal places.)

Step 1

4$ and $\sigma = 26$. We are drawing a random sample of size $n = 55$. We want to find the probability that the sample mean $M$ is less than 145.8. According to the Central Limit Theorem, the distribution of the sample mean $\bar{X}$ is approximately normal with Show more…
