Answer:
C. H0 : p = 0.8 H 1 : p ≠ 0.8 
The test is:_____.
c. two-tailed 
The test statistic is:______p ± z (base alpha by 2) 
The p-value is:_____. 0.09887 
Based on this we:_____.
B. Reject the null hypothesis.
Step-by-step explanation:
We formulate null and alternative hypotheses as  proportion of people who own cats is significantly different than 80%.
 H0 : p = 0.8 H 1 : p ≠ 0.8 
The alternative hypothesis H1 is that the 80% of the  proportion is different and null hypothesis is , it is same. 
For a two tailed test for significance level = 0.2 we have critical value  ± 1.28.
We have alpha equal to 0.2  for a two tailed test . We divided alpha with 2 to get the answer for a two tailed test. When divided by two it gives 0.1 and the corresponding value is ± 1.28
The test statistic is 
p ± z (base alpha by 2) 
Where p = 0.8 , q = 1-p= 1-0.8= 0.2
n= 200
Putting the values
0.8 ± 1.28 
0.8 ± 0.03620
0.8362, 0.7638
As the calculated value of z lies within the critical region  we reject the null hypothesis.

Answer:
(1 ÷ 1/6) * 6
36 pieces of pizza 
Step-by-step explanation:
Given that :
Number of pizzas ordered = 6
Divisions per pizza = 1/6 ; 
Hence, 1 full pizza is divided into 1 ÷ 1/6 = 1 * 6/1 = 6 pieces
6 * 1/6(1)
The total pieces of pizzas equals :
6 pieces per pizza * number of pizzas
6 * 6
= 36 pieces of pizza 
 
        
             
        
        
        
Answer: centroid
Reasoning: The centroid is the point of concurrency of the three medians in a triangle.
