The RP government reported that for families in a certain rural area, the distribution of weekly expenses for food consumed away from home has an average of P237.60 and a standard deviation of P50.40. An economist randomly sampled 100 families for their outside-home food expenses for a week.  1. What is the distribution of the mean weekly outside-home food expenses for the 100 families?  2. What is the probability that the sample mean weekly expenses will be at least P252? Just provide the z value
