WebUsing a standard normal distribution table or calculator, we can find that the z-score that corresponds to a probability of 0.75 is approximately 0.6745. Next, we can use the formula to solve for M: M = mean + z * standard deviation M = 60000 + 0.6745 * 15000 M = 16717.5 + 60000 M = 76717.5 church in revelation verses
