Answer:
see explanation
Step-by-step explanation:
Note the common difference d between consecutive terms of the sequence
8 - 6 = 10 - 8 = 2
This indicates that the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 6 and d = 2, thus
= 6 + 2(n - 1) = 6 + 2n - 2 = 2n + 4 ← explicit formula
Hence
= (2 × 130) + 4 = 260 + 4 = 264
Answer:
C. Test for Goodness-of-fit.
Step-by-step explanation:
C. Test for Goodness-of-fit would be most appropriate for the given situation.
A. Test Of Homogeneity.
The value of q is large when the sample variances differ greatly and is zero when all variances are zero . Sample variances do not differ greatly in the given question.
B. Test for Independence.
The chi square is used to test the hypothesis about the independence of two variables each of which is classified into number of attributes. They are not classified into attributes.
C. Test for Goodness-of-fit.
The chi square test is applicable when the cell probabilities depend upon unknown parameters provided that the unknown parameters are replaced with their estimates and provided that one degree of freedom is deducted for each parameter estimated.
Answer:
Option A is correct.
The value of r = -0.7 represents the strongest negative correlation.
Step-by-step explanation:
A correlation is a value that describes a relationship between two things or variables.
Strongest Negative Correlation says that closer a negative correlation to -1, the stronger the relationship between the two variables.
From the options, we have only two negative values i.e, r= -0.7 and r= -0.22.
We have to find the strongest negative correlation r-value.
By the definition, you can see that -0.7 is very closer to -1 ,
therefore, the value of r = -0.7 represents the strongest negative correlation.
Couldn't it be 54, 53 52, or 51
Y - y₁ = m (x-x₁)
y - (-5) = 0 (x-2)
y + 5 = 0
y = -5
