The census bureau reported that the mean household income in Hayward in 2019 was $86,744 with a standard deviation of $18,700. A simple random sample of 150 households from Hayward had a mean income of $89,396 with a standard deviation of $23,156. Find the probability that a sample of this size will indicate a mean of $89,396 or more?
