Answer:
The number of drips per minute needed to deliver the medication at the prescribed dosage is 50 drips per minute
Step-by-step explanation:
The given parameters are;
The volume of the prescribed medication to delivered through IV = 800 mL
The duration over which the drug is to be delivered = 8 hours
The rate at which the IV delivers the medication = 30 drips/1 mL
800 mL = 800 × 1 mL
Therefore, the total number of drips in 800 mL= 800 mL × 30 drips/mL = 24,000 drips
The rate at which the drug is delivered = 800 mL/(8 hours) = 100 mL/hr = 100/60 mL/minute = 10/6 mL/minute
The total number of drips in 10/6 mL= 10/6 mL × 30 drips/mL = 50 drips
∴ The rate at which the medication needs to be delivered = 10/6 mL/minute = 50 drips/minute
The number of drips per minute needed to deliver the medication at the prescribed dosage of 800 mL/(8 hours) = 10/6 mL/minute = 50 drips per minute.

<u>Step-by-step explanation:</u>
There are 5 men and 7 women, which is a total of 12 people. Finding the probability that none of the four people are women is the same as saying that all four people are men.
Answer:
Step-by-step explanation:
1) The confidence interval is calculated as the following
Hence, the confidence interval is 
11) Under two sid t-tailed test, the null hypothesis
Against the alternative hypothesis
Under null hypothesis
The degree of freedom is n - 1 = 140
From the t - table at 5% level of significance under two - tail is 1.96
Since , calculated value is lowe than the tabulated value, we do not reject the null hypothesis.
