Given a set of data sorted from smallest to largest, define the first, second, and third quartiles. O The first quartile is the area within one standard deviation of the mean. The second quartile is the area within two standard deviations of the mean. The third quartile is the area within three standard deviations of the mean. O The first quartile is the mean of the lower half of the data below the median. The second quartile is the median. The third quartile is the mean of the upper half of the data above the median. O The first quartile is the area that contains the 25% of all values that are closest to the mean. The second quartile is the area that contains the 50% of all values that are closest to the mean. The third quartile is the area that contains the 75% of all values that are closest to the mean. The first quartile is the minimum value.

I bought a new gas lawn mower the other day. This new mower mows faster than the old electric (environmental) one. Why, you ask? It is because the old mower cut a 21 inch path, while the new one cuts a 22 inch path. So how much time did I save? Look at some facts. My lawn is a rectangle measuring 150 feet by 105 feet I mow the lawn in strips and always in the same direction (length or width) My walking speed is 120 feet/minute It takes 5 seconds to turn around after each strip How much time did I save if I mow back and forth along the width or if I mow back and forth along the length? Pick one and figure it out. My neighbor does not like minutes the noise it makes, but I do!

Please describe the answers step by step since it is difficult to figure it out since the answers are cut off.
