Answer:
The sample size is 4
Step-by-step explanation:
Null hypothesis: The mean is 2
Alternate hypothesis: The mean is less than 2
Mean = 3
sd = sqrt(variance) = sqrt(4) = 2
At 95% confidence level, t-value is 1.960
Assuming the lower bound of the mean is 1.04
Lower bound = mean - (t×sd/√n)
1.04 = 3 - (1.96×2/√n)
3.92/√n = 3 - 1.04
3.92/√n = 1.96
√n = 3.92/1.96
√n = 2
n = 2^2
n = 4
Answer:
what is the question?????????????????????
Answer:
<em>n= Total number of packages on trucks= 6096</em>
<em>n = T x P (Model Equation)</em>
Step-by-step explanation:
No. Of delivery trucks = T = 127
Package on each truck = P = 48
Total number of packages on trucks =n= ?
Each truck contains 48 packages and total trucks were 127, to find total number of packages on trucks , we just need to multiply the number of trucks with the number of package on each truck.
Total number of packages on trucks =n= (No. Of delivery trucks) x (Package on each truck)
n = T x P (Model Equation)
n= 127 x 48
n= 6096 (Total number of packages on trucks)
The correct answer is the fourth option.
Given is a scatter graph with points marked on the graph. The x axis shows the dependent variable and y axis the independent variable
From the graph we see that there seems to be a linear relationship but not fully perfect. Because so many points deviate from the line we can only say that there is a moderate association.
Whenever x increases y increases also the linear regression line of fit has a positive scope.
Hence there is a positive association between variable x and variable Y.
Answer:
Step-by-step explanation:
if we have a right triangle, and isosceles
c^2=a^2+b^2 , in this case of isosceles, a=b
c^2=2a^2
1^2=
1=a
a=1/=/2
