Answer:
The one tailed P-value for the test statistic for df = n-1 = 33-1 = 32 is
Step-by-step explanation:
We are given:
Claim: 
°F
Now we can use the technology like excel to find the P-value. The excel function is given below:
Where:
1.021 is the test statistic
32 is the degrees of freedom
1 stands for one tailed alternative hypothesis.
Therefore, the P-value is 0.1575
The least-square regression line has a slope of:
m=(nΣxy-ΣyΣx)/(nΣx²-ΣxΣx)
and a y-intercept of:
b=(Σy-mΣx)/n
In this case: n=7, Σxy=4899, Σy=391, Σx=85, Σx²=1153 so
m=(7(4899)-391*85)/(7(1153)-85*85))=1058/846
b=(391*846-85*1058)/(7*846)=34408/846
So the line of best fit is:
y=(1058x+34408)/846 and if we approximated this as your answers see to have done....
y=1.25x+40.67
Answer:
x ≠ - 2, 5
Step-by-step explanation:
The restrictions occur in the denominator which cannot be zero as this would make the function undefined. Equating the denominator to zero and solving gives the values that x cannot be.
solve x² - 3x - 10 = 0 ⇒ (x - 5(x + 2) = 0 ⇒ x = -2, 5
