Answer:
Nutz in my opinion
Step-by-step explanation:
Val covers greater distance because 2 3/5 x 4 = 10 2/5. Bill only ran 10 miles so Val covered 2/5 more miles than him.
Answer:
The correct value is t* = 2.797.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a two-tailed confidence level of
. So we have T = 2.797.
Answer:
Step-by-step explanation:
n = sample size = 5
a) Let us determine the sum





Now we can determine 




The estimate b of the slope β is the ratio of
and 


The mean is the sum of all value divide by number of values


The estimate a of the intercept is


General least square equation;

replace alpha by a = 3 and beta by b = 0.67 in general least equation
y = a + bx
195.9 + 0.67x
b)
<em>Scatter plot is shown in the attached file</em>
x is on the horizontal axis
y is n the vertical axis
The degree of freedom of regression is 1
because we use one variable s predictor variable

The degree of freedom of error is the sample size n decrease by 2

Total df is equal to the sum of seperate degree of freedom dfR and dfE
total df = 1 +3 4

Total SS =Syy= 45007.2
SSE + Total SS = SSR
= 45007.2 - 43146.9296
= 1860.2705
