Over 30-day period, the mean temperature in springville was 78f with a standard deviation of 4f and the mean temp erasure in dakota was 74.5f with a standard deviation of 6.8f. what statement best describes the data? the temperatures were more consistent in dakota. the temperatures were more consistent in springville. the temperatures were consistency in springville and dakota.

The temperatures were more consistent in Springville

Step-by-step explanation:

This question is on consistency of data

Generally, consistency of a data set is measured by determining the range, the variance or the standard deviation.In this case, we will use the standard deviation.

A small standard deviation means higher consistence.A lower standard deviation  will mean easy to predict a value because most of the values are closer to the average value.When the variations are less, a better analysis can be performed on a set of data.

Temperatures were more consistent in Springville that had a standard variation of 4F compared to Dakota that had a standard deviation of 6.8F

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
