Answer:
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 20 - 1 = 19
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 19 degrees of freedom(y-axis) and a confidence level of . So we have T = 2.861.
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
The format of the confidence interval is:
In which is the sample mean
So
Answer:
60 days
Step-by-step explanation:
Let's call h the daily dose of medication that a diabetic person should administer.
We know that:
h = 0.0005 L/day
We know that 0.03 liters is what the social institution provides.
Then we can raise the following equation:
hx = 0.03
Where x is the number of days
So:
x = 60 days.
After 60 days you will have to return for more doses
