Answer: Two-tailed test.
Population mean is the parameter which is tested.
Step-by-step explanation:
Given : 
We know that , the alternative hypothesis (
) indicates kind of the hypothesis test we need to perform whether left-tailed, right-tailed, or two-tailed.
Here, the alternative hypothesis () is two-tailed, so the hypothesis test is a two-tailed test.
Also, the parameter present in the hypothesis is 
which is a symbol to represent the population mean.
Thus , Population mean is the parameter which is tested.
Answer:Kyle’s claim is not reasonable
Step-by-step explanation:
Total length of the string of the necklace that Kyle covered with black beads is 5/8.
Total length of the string of the necklace that Kyle covered with white beads is 1/4.
Total length of the string of the necklace that Kyle covered with black beads and white beads is would be
1/4 + 5/8 = 7/8 = 0.875
Kyle thought that he will cover 6/12 of the string with beads. 6/12 = 0.5
It means that he covered more than 6/12. Kyle's claim was wrong
Answer:
a = 3, b = -1, c = 10
Step-by-step explanation:
Let the three numbers be a, b and c.
Equation 1: a + b + c = 12
Equation 2: a + 2b + 3c = 31
Equation 3: 9b + c = 1
Equation 2 - Equation 1:
Equation 4: b + 2c = 19
Equation 3 times by the number 2
Equation 5: 18b + 2c = 2
Equation 5 - Equation 4
17b = -17
b = -1
Substitute into Equation 4:
2c - 1 = 19
2c = 20
c = 10
Substitute into Equation 1:
a + b + c = 12
a - 1 + 10 = 12
a = 3
Answer:
79 is the value
Step-by-step explanation:
Answer:
They are equal to each other, because one vertical angle is a reflection of the other. True
They are not equal to each other, because one vertical angle is not a reflection of the other. False
They are equal to each other, because one vertical angle is supplementary to the other. False
They are not equal to each other, because one vertical angle is not supplementary to the other. False
