Divide 2748 by 6 to find how much miles it travels in one hour. Then multiply that answer by 2 to find the total amount of miles traveled for 2 hours.

You can set up a proportion in order to get this answer. So if you're able to travel 2748 miles in 6 hours, then divide 2748 by 3  in order to get the distance for 2 hours. This should be equal to 916 miles in 2 hours.

<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.
