A client of a commercial rose grower has been keeping records on the shelf-life of a rose. The client sent the following frequency distribution to the grower.

Rose Shelf-Life
Days of Shelf-Life Frequency fifi
1 – 5 3
6 – 10 3
11 – 15 7
16 – 20 8
21 – 25 4
2626 – 3030 11

Step 1 of 2 :  

Calculate the population mean for the shelf-life. Round your answer to two decimal places, if necessary.

Step 2 of 2 :

Calculate the population standard deviation for the shelf-life. Round your answer to two decimal places, if necessary.

The liquid chlorine added to swimming pools to combat algae has a relatively short shelf life before it loses its effectiveness. Records indicate that the mean shelf life of a 5-gallon jug of chlorine is 2,160 hours (90 days). As an experiment, Holdlonger was added to the chlorine to find whether it would increase the shelf life. A sample of nine jugs of chlorine had these shelf lives (in hours): 2,159 2,170 2,180 2,179 2,160 2,167 2,171 2,181 2,185   Click...
