Answer:
Assuming you want to find u, u = 9.29
Step-by-step explanation:
u - 5.3 = 3.99
Add 5.3 to both sides.
u = 3.99 + 5.3
u = 9.29
Answer:
df.= 28
P - value = 0.0124 < 0.05
There is a difference between the mean of the well-being measure for the children of alcoholics, and a mean of the control group.
Step-by-step explanation:
As the given test is dependent or paired test the degrees of freedom is n-1 = 20-1 = 28
The reported t = 2.67
The P value for ∝= 0.05 at calculated t= 2.67 and 28 d.f is 0.0124 which is less than 0.05 .
The null hypothesis is rejected.
The null hypothesis is that there is no difference between the means of the two samples.
H0: u1 = u2
The alternate hypotheis is accepted that there is difference between the means of the two samples.
Ha: u1≠ u2
There is a difference between the mean of the well-being measure for the children of alcoholics, and a mean of the control group.
Answer: C
Step-by-step explanation:
The red graph is the result of reflecting the graph of y=f(x) across the x-axis and then translating 1 unit to the right.
Using the information given, it is found that the class width for this frequency distribution table is of 1.
In this problem, these following classes are given:
0 – 1 14
2 – 3 1
4 – 5 8
6 – 7 12
8 – 9 12
The classes not given, which are 1 - 2, 3 - 4 and 5 - 6, have values of 0.
The <u>difference between the bounds of the classes is of 1</u>, thus, the class width is of 1.
