The answer would be -1 14/15
The 99% confidence interval for the true mean is given by:

where:

is the sample mean = 69.7

is the standard deviation = 2.8

is the test statistics = 2.58 for for 99% confidentce interval.
n is the sample size = 772.
Therefore, the 99% confidence interval is:
Answer: Please refer to:
- A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. ... Forces only exist as a result of an interaction.
- Force is a vector quantity, with both direction and magnitude. It is defined as Mass x Acceleration = Force.
+ The SI unit of force is the newton (N); defined as the unit of force which would give to a mass of one kilogram an acceleration of 1 meter per second squared.
- two effects of force:
+ It can change the state of movement of the body on which force is applied, i.e. it can move a stationary object or stop a moving object.
+ It can change the shape and size of an object.
