Bill Board is trying to reduce his sodium intake to an average of 2300 mg.
Fed [463]

Answer:

mean average = 2542.5 mg

1330 mg

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 = \frac{2150+3005+2700+2315}{4}

mean average = \frac{10170}{4}

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 = \frac{2150+3005+2700+2315+y}{5}\\2300 = \frac{2150+3005+2700+2315+y}{5}

2300*5 =2150+3005+2700+2315+y

11500 = 10170 +y

11500-10170 =y

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
