8. Find TN.
1 answer:
The measure of TN from the given figure is 22 units
<h3>The centroid of a triangle</h3>According to the given triangle:
- MT = TP
Given the following:
MT = 6x - 56
TP = 3x - 17
Equate
6x - 56 = 3x - 17
6x - 3x = -17 + 56
3x = 56
x =39/3
x = 13
Get the measure of TN:
TN = MT
TN = 6(13) - 56
TN = 78 - 56
TN = 22
Hence the measure of TN is 22 units

The degrees of freedom are given by:
The significance level is and then the critical value can be founded in th chi square table we need a quantile that accumulates 0.05 of the area in the right tail of the distribution and for this case is:
And if the chi square statistic is higher than the critical value we can reject the null hypothesis in favor of the alternative.
Step-by-step explanation:
We have the followign system of hypothesis:
