Answer:
mean average = 2542.5 mg
1330 mg
Step-by-step explanation:
The patient's average daily intake of sodium for those 4 days can be calculated by taking the mean average of the sample amounts given over the number of the total days.
![mean average = (2150+3005+2700+2315)/(4)](https://img.qammunity.org/2021/formulas/advanced-placement-ap/middle-school/d3bi03wp80f40v1dykb9mxwmj64hr9f4td.png)
![mean average = (10170)/(4)](https://img.qammunity.org/2021/formulas/advanced-placement-ap/middle-school/l6t5b56vjhtht1qb38tumgqgmnlm4yi13k.png)
mean average = 2542.5 mg
Therefore the patient's average daily intake of sodium for those 4 days = 2542.5 mg
What is the patient’s average daily intake of sodium for those 4 days?
What would his 5th day sodium intake need to be to drop him below an average of 2300 mg
given that mean average = 2300; we can also determine the fifth day sodium intake as follows:
![mean average = (2150+3005+2700+2315+y)/(5)\\2300 = (2150+3005+2700+2315+y)/(5)](https://img.qammunity.org/2021/formulas/advanced-placement-ap/middle-school/jiuc6z5dwskdcn530s7dor7igfgtyyhmml.png)
![2300*5 =2150+3005+2700+2315+y](https://img.qammunity.org/2021/formulas/advanced-placement-ap/middle-school/me915ow3rfp0znxwu6g16p7cvaw8lk9ong.png)
![11500 = 10170 +y](https://img.qammunity.org/2021/formulas/advanced-placement-ap/middle-school/2v17mx0vvw86ozstvmmp5e7j9p93ipnt4z.png)
![11500-10170 =y](https://img.qammunity.org/2021/formulas/advanced-placement-ap/middle-school/tje00y4bf7enwigi6v3tff5id5je9wfb0c.png)
y = 1330 mg
Hence, his sodium intake for the fifth day will be 1330 in order to drop him below an average of 2300 mg
