Answer:
C. At the 0.01 level of significance, the mean mass of the apples grown in the farmer's orchard is different from 100g.
Step-by-step explanation:
The null hypothesis is:
Because of the claim of the farmer.
The alternate hypothesis is:
The alternate hypothesis tests the farmer's claim at a significance level.
The results are calculated to be statistically significant at the 0.01 level.
This means that at the 0.01 level, the null hypothesis is rejected, that is, the mean mass of the farmer's orchard is different from 100. Since it is significant at the 0.01 level, it will be significant at the 0.05, 0.1, and increasing levels. So the correct answer is given by option C.
Answer:
c) v.v
Step-by-step explanation:
The Dot product also known as scalar product or inner product is the multiplication of two equal length vectors which results in a scalar.
Mathematically,
where and
are the magnitudes of the vectors a and b
is the angle between vectors a and b
If a and b are in the same direction then
if a and b are orthogonal (90°) then
To represent the square of the magnitude of a vector v
Hence option c is the correct answer
a. v/|v|
Here vector v is divided by its own magnitude
b. v.|v|
Here vector v is multiplied by its own magnitude
c. v.v
Represents the square of the magnitude of vector v
d. v^2.v^2
Represents the dot product of square of vector v
