Multiple 1/4 x 1/8 to get your answer
Reasonable because the three items altogether cost about $40
Answer:
Step-by-step explanation:
Answer: ( 8.11 , 9.69)
the 95% confidence interval of the true mean weight
= ( 8.11 , 9.69)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 8.9
Standard deviation r = 0.9
Number of samples n = 5
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
8.9+/-1.96(0.9/√5)
8.9+/-1.96(0.4025)
8.9+/- 0.79
= ( 8.11 , 9.69)
Therefore at 95% confidence interval (a,b) = ( 8.11 , 9.69)
Answer: The 36th caller will be the first one to win both
Step-by-step explanation:
Given: A radio station is having a promotion in which every 12th caller receives a free concert ticket and every 9th caller receives a limo ride.
To find which caller would be the first one to win both, we will find the LCM.
Prime factorization of 9 and 12:
12 = 3x 2x 2
9 = 3x 3
[Where LCM=Least common multiple]
Therefore, the 36th caller will be the first one to win both.
