Statistics should be used because the temperature would vary during January and you would want to give an accurate answer.
Answer:
Between 12.614 years and 16.386 years
Step-by-step explanation:
Given that:
Mean age (μ) = 14.5 years, standard deviation (σ) = 4.6 years, number o sample (n) and the confidence interval (c) = 90% = 0,9
α = 1 -c = 1 -0.9 = 0.1
The z score of 
is the same as the z score of 0.45 (0.5 - 0.05). This can be gotten from the probability distribution table. Therefore:
The margin of error (e) = 
= 
The interval = μ ± e = 14.5 ± 1.886 = (12.614 ,16.386)

Step-by-step explanation:
Answer:
Sampling interval = 9.323
Step-by-step explanation:
Given that:
Population size, N = 9500
Require sample, n = 1019
Sampling interval :
Population size / required sample size
Sampling interval = 9500 / 1019 = 9.3228
Interpretation :
In other to obtain a sample of 1019 drawn systematically from the population, a sample will be drawn at every 9.323 units from the population of 9500
