Answer:
There is a linear correlation between the chest size and weight
Proportion of the variation in weight can be explained by the linear relationship between weight and chest size is 0.006724 .
Step-by-step explanation:
Null Hypothesis: = There is no linear correlation between the chest size and weight
Alternative Hypothesis : =There is a linear correlation between the chest size and weight
The value of the linear correlation coefficient is r=0.882.
n = 8
Formula :
Degree of freedom = n-1 = 8-1 = 7
α =0.05
so, p value is 2.365
t calculated > t critical
So, we reject the null hypothesis
So, There is a linear correlation between the chest size and weight
The proportion of the variation in weight can be explained by the linear relationship between weight and chest size =
Hence proportion of the variation in weight can be explained by the linear relationship between weight and chest size is 0.006724 and There is a linear correlation between the chest size and weight
The formula to find slope is (y2-y2)/(x2-x1)
You can remember it like this: "If you want to be wise, remember rise over run, which is y's over x's."
The next step is to determine which point is (x1,y1) and which is (x2,y2).
We do this by determining which point has the biggest x value: (8,7)
Now we plug it into the formula: (8-4)/(7-1)
Simplify and we get: 4/6 or 2/3
Voila! You have your slope: 2/3
Hope this helps, and May the Force Be With You.
Answer:
Step-by-step explanation:
To find the expression equal to the given, we will simplify the original.
Given:
Simplify:
Answer:
Each die has six numbers, the total number of possible combinations is 6 * 6 = 36
The combinations in which you can get a sum of 5 are: 1 &4, 2 & 3, 4 &1, 3 &2
There are 4 different combinations of getting a sum of 5.
The probability would be 4/36, which reduces to 1/9
