Answer: -1.78
Step-by-step explanation:
As per given description, we have
Population proportion : 
Sample size : n= 500
Sample proportion : 
Test statistic for population proportion :-

Hence, the test statistic for this hypothesis test for a proportion= -1.78
Sum of two angles that are supplementary = 180°
Let the smaller angle be = x


<h3>Their sum :</h3>






Using this let us find the measures of the smaller angle and bigger angle .


∴ The measure of the two angles are = 21° and 159° .
N+ 0.2n = 1.2nn = (1.2n) - (1/6)*(1.2n)
1/6 = 16.667%
All together he made 23.40
One third of $17.55 is $5.85
When you add $17.55 and $5.85 together you get $23.40
