A meteorological office keeps records of the annual precipitation in different cities. For one city, the mean annual precipitation is 24.7 inches and the standard deviation of the annual precipitation amounts is 5.6. Let x represent the annual precipitation in that city. Determine the z-score for an annual precipitation in that city of 39.9 inches. Round your answer to two decimal places. 12.74 -2.71 2.71 1.41

In California, we need more rain to sustain the health of our natural environment, agriculture, and economy. A group of statistics students at Oxnard College recorded the amount of rain during the 2016-2017 school year, measuring the intensity in inches. The results were as follows: Inches of Rain Frequency 1 1 2 2 3 4 4 3 5 2 6 3 The mean (x̄) rain intensity: inches (Please show your answer to 1 decimal place.) The median rain intensity: inches The mode rain intensity: inches (Please separate your answers by ',' in the bimodal situation. Enter DNE if there is no mode or if there are more than two modes.)
