Answer:
A. The first equation is for sample data; the second equation is for a population.
Step-by-step explanation:
The first equation is y = , this is the equation for sample data as the intercept (
) and the slope parameter(
) both are calculated then we have got this and these values are not taken as given.
The Second equation is , this is the equation for population data as we can't calculate these
and
as we take these values as given and also we do testing for
parameter using t test and it is sure that testing is always done on population data not on sample data.
To find the area of the trapezoid, we only need the quantities a1 (long base), a2(short base) and h(height).
Area=(1/2)(a1+a2)*h
=(1/2)(9.9+4.7)(5.6)
=40.88 mm ²
Not sure what's expected to give for "type". Perhaps trapezoid or trapezium.
