Forty families gathered for a fund-raising event. Suppose the individual contribution for each family is normally distributed with a mean and a standard deviation of $125 and $32, respectively. The organizers would call this event a success if the total contributions exceed $5,400. What is the probability that this fund-raising event is a success? (You may find it useful to reference the z table. Round final answer to 4 decimal places.) Probability

Solve using R Caculator The average hourly wage for manufacturing workers in the United States is $16.17 per hour, with a standard deviation of $1.42. Assume the data is normally distributed. What is the probability that a randomly chosen manufacturing worker makes more than $15.95 an hour?List the z-scores needed to calculate the result. If there is more than one z-score, separate the values with a comma. There is a ___ chance that a randomly chosen manufacturing worker makes more than $15.95 per hour.
