Identify the outlier in the data. then find the mean when the outlier is included and when it is not included. 68, 63, 67, 66, 65, 87, 69, 61, 86, 82, 28 outlier is 28; mean with outlier = 74.2; mean without outlier = 71.4 outlier is 28; mean with outlier = 67.5; mean without outlier = 71.4 outlier is 28; mean with outlier = 67; mean without outlier = 67.5 outlier is 28; mean with outlier = 67.5; mean without outlier = 64.9

Without is 64.9

Outlier is 28.

Step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

answer: what are the following choices
