Answer:
You inject 60.9628 milliliters of dosage
Step-by-step explanation:
1 pound = 0.453592kg,
Patient's weight in pounds = 168
Patient's weight in kg =
Now we are given that The dosage is 0.4 mg per kilogram of bod
So, dosage =
1 microgram = 0.001 mg
Concentration of drug =
Now we are supposed to find How many milliliters (= cc) are you to inject?
So,milliliters of dosage required to inject =
Hence you inject 60.9628 milliliters of dosage
Answer:
The margin of error for the true mean number of hours a teenager spends on their phone is of 0.4 hours a day.
Step-by-step explanation:
We have the standard deviation of the saple, 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 = 50 - 1 = 49
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 49 degrees of freedom(y-axis) and a confidence level of . So we have T = 2
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
The margin of error for the true mean number of hours a teenager spends on their phone is of 0.4 hours a day.
