Yes she actually read for 12.25 hourse
Answer:
Step-by-step explanation:
We are given that
Standard deviation, s=11.0995 kg
Sample size, n=10
We have to find the variance of their weights.
We know that
Variance=
Using the formula
The variance of their weights
=
=
Hence, the variance of their weights=
In Physics, the usual pattern or principle for pressure suggests that as the force increases and the area decreases, the pressure increases which is dependent as to the interval of both force and area's intensifies or diminishes. Though in this problem, if we base on the given data it seems that the pressure is currently increasing and is faced by a positive correlation at almost 50% in rate as evident that when the 33 ft increased to about 66ft the latter simultaneously rise with it.
