A 40 gram sample of a substance that's used for drug research has a k-value of
0.1472.
N = Noe
-kt
No = initial mass (at time t = 0)
N = mass at time t
:
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days

Anull hypothesis states that the difference between 8 hours of sleep and 3 hours of sleep has no effect on the number of pictures a student will remember during a picture memory interface test (pmit). examining the mit database, an extremely small t-value of 0.1611 is found. this t-value is much smaller than the smallest t-value on the chart for p-value reference. from this information we can: select one: a. accept the null hypothesis because the p-value obtained shows that the difference between the two groups being tested is not statistically significant b. accept the null hypothesis because the p-value obtained was statistically significant c. reject the null hypothesis because of the p-value obtained d. reject the null hypothesis because the data obtained is statistically significant
