We are given the expression of the equation of a circle that is x2 + y2 + 14x + 2y + 14 = 0. Using ocmpleting the squares:
x2 + y2 + 14x + 2y + 14 = 0(x+7)^2 + (y+1) ^2 = -14 + 49 + 1(x+7)^2 + (y+1) ^2 = 36 center thus is at (-7,-1) and the radius is equal ot square root of 36 equal to 6.
In a statistical test, the null hypothesis to be made is
that the sample proportions do not have any significant differences, which
means an equal distribution. This is only rejected when the estimate is equal
or less than 0.95. But since in this case it is >0.95, so therefore the null
hypothesis is not rejected. Therefore:
<span>False</span>
