Why are students typically tired at school?

2 answers:

8 0

Not sure if there is a correct answer here, but here are some reasons:

1. They haven't slept well the night before, due to homework, projects, and even using devices (like our phone) for too long. Waking up early for school will result in sleeping students in class. Even the environment of the class can put them to sleep (ex. dim lights, quiet students, etc.)

2. They are bored. Someone who hates math or history will start to yawn as soon as the teacher begins explaining (ex. even if they were just so energetic in gym class the period before).

Alamos Co. exchanged equipments and $18,200 cash for a similar equipment

The book value of the old equipment is $81,100

The fair value of the old equipment is $91,900

The gain/loss recorded by Alamos can be calculated as follows

= Fair value-book value

= $91,900-$81,100

= $10,800

But since the exchange lacks a commercial substance then, no amount of gain or loss will be recognized/recorded.

Hence Alamos Corporation recorded a gain of $0

Since the calculated value of F= 5.733 falls in the critical region we reject the null hypothesis and conclude all three means are not equal.

The results of excel are:

Anova: Single Factor

SUMMARY

Groups Count Sum Average Variance

Column 1 5 54 10.8 1.2

Column 2 5 40 8 2

Column 3 5 42 8.4 2.8

1) Let the null and alternate hypotheses be

H0: u1=u2=u3 i.e all the three means are equal and

Ha: Not all three means are equal

2) The significance level is set at ∝ =0.05

3)The test statistic to use is

F= sb²/ sw²

which has F distribution with v1= k-1 →3-1=2 and v2= n-k →15-3=12 degrees of freedom

After calculations the following table is obtained.

Within Groups 24 12 2

Total 46.93 14

4) The critical region is F ≥ F(0.05, 2,12) = 3.885

5) Since the calculated value of F= 5.733 falls in the critical region we reject the null hypothesis and conclude all three means are not equal.
