Question

Temperatures in June in the Paradise City are distributed nearly normally with mean 83 degrees and standard deviation 6 degrees F. Which of the following temperatures would be considered unusual?

• 88.4
• 77
• 82.4
• 95.6
• 80

Answer 1

Answer:

Given,

Mean = 83

Standard deviation = 6

By utilizing empirical rule,

95% may lies in interval b/w (u +/- 2)

i.e.,

= (83 +/- 2*6)

= (83 +/- 12)

= (83 - 12 , 83 + 12)

= (71 , 95)

So 95.6 doesn't lies in the interval, It is unusual observation.

i.e.,

Option D is right option.
