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)

i cnt see the question and its blurry and can i get the crown thing
First, review how you would go about finding an average. If you look only at the 5 scores given, 16, 12, 15, 13 and 17, you'd add these up and divide the sum by the number of scores (5).
Now suppose there's a 6th game and your score is x.
Add up the first 5 scores as before, and then add x to indicate the 6th score. Divide this sum by 6 (because there are now 6 scores).
Solve the resulting equation for x. Show your work, please.
