Answer:
n > 96
Therefore, the number of samples should be more than 96 for the width of their confidence interval to be no more than 10mg
Step-by-step explanation:
Given;
Standard deviation r= 25mg
Width of confidence interval w= 10mg
Confidence interval of 95%
Margin of error E = w/2 = 10mg/2 = 5mg
Z at 95% = 1.96
Margin of error E = Z(r/√n)
n = (Z×r/E)^2
n = (1.96 × 25/5)^2
n = (9.8)^2
n = 96.04
n > 96
Therefore, the number of samples should be more than 96 for the width of their confidence interval to be no more than 10mg

Step-by-step explanation:
Answer:
D)
Step-by-step explanation:
Because
a) 10 = 2(5) = 10
b) 10 = 5 + 5 = 10
c) 10 = 15 -5 = 10
d) 10 = 5 - 5 = 0 the result is not equivalent
Answer:
500
Step-by-step explanation:
if you take 4,000 miles and divide it by 8 hours, it will give you 500, so that how we figure the speed.
The final answer is 500.
Answer:
35 mililiters
Step-by-step explanation:
Given
Required
Accumulated amount from t = 0 to 2
This implies that, we substitute the values of t from 0 to 2 in the function
The accumulated sand (r) is:
