An ANOVA procedure is used for data obtained from four populations. Four samples, each comprised of 30 observations, were taken from the four populations. The numerator and denominator (respectively) degrees of freedom for the critical value of F are _____.
Answers
Answer:
Step-by-step explanation:
Given that an ANOVA procedure is used for data obtained from four populations. Four samples, each comprised of 30 observations, were taken from the four populations.
Hence total observations are 30*4 =120
No of groups = 3
Hence numerator df = 3-1 =2
Now total degrees of freedom = 120-1 =119
So denominator degrees of freedom = 119-2 = 117
Thus F statistic will have numerator as 2 degrees of freedom and denominator as 117 degrees of freedom.

null hypothesis is rejected
The council decides that it will increase the transportation budget if the amount of waiting time for drivers is not exceeds 18 minutes
Step-by-step explanation:
Step (i):-
A sample of 26 main roads results in a mean waiting time of 21.1 minutes with a sample standard deviation of 5.4 minutes.
Given sample size 'n' = 26
The mean of the sample 'x⁻ = 21.1 min
Standard deviation of the sample 'S' = 5.4 min
The Population mean 'μ' = 18min
Step(ii):-
Null hypothesis: H₀ : The council decides that it will increase the transportation budget if the amount of waiting time for drivers exceeds 18 minutes.
'μ' > 18min
Alternative hypothesis :H₁:
'μ' <18min
Level of significance : ∝=0.05
Degrees of freedom γ = n-1 = 26-1 =25
The test statistic
t = 2.9272
Step(iii):-
The tabulated value t = 1.708 at 25 degrees of freedom
t = 2.9272 > 1.708 at 25 degrees of freedom
Null hypothesis is rejected at 5% significance level of significance
Conclusion:-
The council decides that it will increase the transportation budget if the amount of waiting time for drivers is not exceeds 18 minutes

Answer: Then the two possible values of x are 53 and -14
Step-by-step explanation:
When we have a set of numbers
{a, b, c, d, e}
The range will be equal to the difference between the larger number and the smaller number.
In our case, the set is:
{26, 33, 46, x, 9, 7, 10, 11}
First, we need to see than largest and smallest numbers in the set (ignoring x)
The largest is 46
the smallest is 7.
Now, if we considerate that x is the smallest number in the set, we will have that:
46 - x = 60
x = 46 - 60 = -14
If x is the largest number on the set, we have that:
x - 7 = 60
x = 60 - 7 = 53
Then the two possible values of x are 53 and -14

Base angles of an isosceles triangle are equal.
This:
The angle of the triangle to our right, which is the third unequal angle = 180 - 2(31)
= 180 - 62
= 118°
The base angle of the triangle to our left = 180 - 118 (angles on a straight line)
= 62°
x = 180 - 2(62)
x = 180 - 124
x = 56°
