the number of minutes it takes lin and noah to finish their tests in german class is collected for the year. lin has a mean of 29.48 minutes and a standard deviation of 5.44 minutes. which dot plot matches the aforementioned description?

Answer

Explanation:

Step1: Recall mean and standard - deviation concepts

The mean is the central value of the data set. The standard - deviation measures the spread of the data. A mean of 29.48 means the data is centered around 29.48, and a standard - deviation of 5.44 means most of the data is within about 29.48±5.44 (i.e., from approximately 24.04 to 34.92).

Step2: Analyze dot - plots

  • For the first dot - plot, the data is centered around 28 - 30 and most of the data is within the range that is consistent with a mean of 29.48 and standard - deviation of 5.44.
  • The second dot - plot is centered around 45 - 50, which is not consistent with a mean of 29.48.
  • The third dot - plot is centered around 55 - 60, which is not consistent with a mean of 29.48.
  • The fourth dot - plot has a more spread - out distribution and is not centered around 29.48.

Answer:

The first dot - plot.
