A student measures the wingspans of 40 local dragonfly specimens selected at random. The sample mean is 6.8 centimeters with a margin of error of 0.9 centimeters. Based on this information, what are plausible values for the mean wingspans of the population of local dragonflies?

Explain or show your reasoning.

Respuesta :

Answer:

6.8 - 0.9 = 5.9

Step-by-step explanation:

5.9 is the only average that seemed reasonable. Hope I helped.

According to the margin of error, it is found that plausible values for the mean wingspans of the population of local dragonflies are between 5.9 and 7.7 cm.

What is the margin of error of a measure?

It is about how much the measure can plausibly differ from the sample mean.

In this problem, considering the sample mean of 6.8 cm and the margin of error of 0.9 cm, the bounds of plausible values are given by:

  • 6.8 cm - 0.9 cm = 5.9 cm.
  • 6.8 cm + 0.9 cm = 7.7 cm.
