  • df= 3
  • NO

<h3>How many variables are involved in the chi-square test?</h3>

a)

This chi-square test only takes into consideration one variable.

b)

The  type of chi-square test this is, is a Goodness of Fit

To test the hypothesis, we must determine whether the actual data conform to the assumed distribution.

The "Goodness-of-Fit" test is a statistical hypothesis test that determines how well the data that was seen resembles the data that was predicted.

c)

Parameter

n = 4

Therefore

Degrees of freedom

df= n - 1

df= 4 - 1

df= 3

d)

In conclusion

Parameters

\alpha = 0.05

df = 3

Hence

Critical value = 7.814728

Test statistic = 6.6

Test statistic < Critical value, .

NO, the result of this test is not statistically significant.

According to the Bureau of Labor Statistics, students who have an after-school job spend an average of 42 fewer minutes per day
IgorLugansk [536]

Answer:

126 hrs

Step-by-step explanation:

-Given the school year has 180 days and the non-working student spends 42 minutes more than the working student.

-The total time during the school year is calculated as;

Total Time=Time/day \times No \ of \ Days\\\\=42\  minutes \times 180\\\\=7560\ minutes

We convert our calculated time in hour(1hr=60 minutes):

=\frac{7560\ mins}{60\ mins}\\\\=126\ hrs

Hence, the average non-working spends an average of 126 hrs that the working student.
