Answer:
H0 : μ ≤ x
H1 : μ > x
The hypothesis :
The null hypothesis, H0 : μ ≤ x
The alternative hypothesis, uses the Friday score samples to compare the hypothesis ;
The alternative hypothesis, H1 : μ > 8
For then null, the mean scores is assumed to be the same, and has such mean of Friday's test score takes the value of the population.
Let the population mean value = x
The alternative hypothesis is the claim that the sampled mean gives a greater value than the population mean :
H1 : μ > x
-6x + 100 = -10x + 160
+ 10x + 10x
4x + 100 = 160
- 100 - 100
4x = 60
4 4
x = 15
If the range is 1, we can assume that every student in that history class studies for a very similar amount of time studying, within 1 minute to be specific.
