A nutrition store in the mall is selling “Memory Booster,” which is a concoction of herbs and minerals that is intended to improve memory performance, but there is no good reason to think it couldn't possibly do the opposite. To test the effectiveness of the herbal mix, a researcher obtains a sample of 8 participants and asks each person to take the suggested dosage each day for 4 weeks. At the end of the 4-week period, each individual takes a standardized memory test. In the general population, the standardized test is known to have a mean of μ = 7

56/112  or 29/56

Step-by-step explanation:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

We have 8 divided into a number as there are 8 participants.

so we can do; 8 x7 = 56 and expand 56 as the median after 4 weeks as 4 weeks is the total

We can divide 56 by 4 and express it must be greater than 8 but no greater than 56-3 = 53 week

Answer mean median and range per week is not conclusive,

Answer mean median per day is not conclusive,

Answer range per day could be shown 112-56=56

As days are 28 x 4 participants = 112 then we have a 50% conclusion to the mean and to the range.

56/112 tests

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
