Hello!
The sum of 5/6 and 1/2 is 1 1/2
5/6 > 3/4 so round it to 1.
1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.
Estimating:
1 + 1/2 = 1 1/2
The difference of 5/6 and 1/2 is 1/2
5/6 > 3/4 so round it to 1.
1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.
Estimating:
1 - 1/2 = 1/2
Hope this helps!

Answer:
37
Step-by-step explanation:
Margin of error = critical value × standard error
For 98% confidence, CV = 2.326 (from t table).
Standard error is σ / √n, where σ is the population standard deviation, and n is the sample size.
Plugging in:
5 = 2.326 × 13 / √n
n = 36.6
Rounding up, n = 37.
