Answer:
The set A = { 1,2,3,4,5,6,7,8,9}
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the set
{ x/x/ is a natural number less than 10 }
<u><em>Natural numbers :</em></u>
The natural numbers are
{ 1,2,3,4,5,6,7,8,9,10,.........}
The set A = { x/x/ is a natural number less than 10 }
51
plug in
8(6)- (-3)
48-(-3)
Answer: D. two-sample z-test for a difference in population proportions
The options for the given questions were missing. The options are as follows:
A one-sample z-test for a sample proportion
B one-sample z-test for a population proportion
A
C two-sample z-test for a difference in sample proportions
D two-sample z-test for a difference in population proportions
Solution:
Sample proportions are used to estimate population proportions.
We are given the sample proportion of students from one state who ordered a yearbook = 70/150
We are also given the sample proportion of students from the other state who ordered a yearbook = 65/100
Since there are 2 samples and we want to investigate if there is a difference between 2 population of students,
Therefore, the most appropriate method for analyzing the results is
D. two-sample z-test for a difference in population proportions
