Answer:
p value from chi square = 0.081
Step-by-step explanation:
Given that sociologists say the percentage of the classic music lovers is about 5%. From the survey, we know that only 83 out of 2000 people listen to the classic music. Let denote the proportion of the classic music lovers. The hypotheses are H0: p=0.05 vs Ha: p≠0.05
p value = 0.09
Instead of this if we do chi square
H0: Proportion of music lovers is 5% and non music lovers is 95%
Ha: Proportions are not as per the estimate
(Two tailed chi square test)
Observed 83 1917 2000
Expected 100 1900 2000
O-E -17 17 0
chi square
(O-E)^2/E 2.89 0.1521 3.0421
df =1
p value from chi square = 0.081
Though p value is not exactly the same, the conclusion in both tests are the same
Answer:
sorry cant help
Step-by-step explanation:
-18 +30s -72t +12u is the answer
Those two angles are complementary - which means they both give us 90
degrees. We know that all three angles in any triangle must be exactly
180 degrees, so the third angle will be 180 - 90 = 90 degrees. It means
that our triangle is a straight triangle. The figure will look more less like in the attachment.

Answer:
1) 2/3
2) y= 2x+4
Step-by-step explanation:
For number one, use the formula
.
Insert the given coordinates into the formula.
7-1/10-1= 6/9
Simplify 6/9.
6/9÷3= 2/3
For the second one, I used desmos calculator.
Hope this helps! :)
