Hello there! The range is 45.
The range is the difference of the greatest value and the least value. To subtract the highest value from the lowest value.
The highest value in this equation: 8
The lowest value in this equation: 53
53 - 8 = 45
So, this means the range is 45.
I hope this helps and have a great rest of your day!
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)
