Usually when encountered with questions that relate with how large a sample should be to yield a significant result is answered by determining the sample size. The sample size is the determination of how much sample is needed for the study to reveal confidence levels of 98% or higher.

Because the population is not given in this proportion, an exact number cannot be revealed. However it might be that the sample is dependent on the nature of the study where Davis plans to exhibit.

What’s the answer to 14?
vfiekz [6]

Answer:

  • |t -(-5)| = 1.5
  • [-6.5, -3.5] = [minimum, maximum]

Step-by-step explanation:

The magnitude of the difference between the temperature (t) and -5 will be 1.5 at the limits:

  |t -(-5)| = 1.5

This is equivalent to two equations:

  • t +5 = -1.5
  • t +5 = 1.5

In each case, the equation is solved by subtracting 5 from both sides:

  • t = -6.5 . . . . minimum allowed temperature
  • t = -3.5 . . . . maximum allowed temperature
