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.
Answer:
c = √746
Step-by-step explanation:
You need to use Pythagorean Theorem (a² + b² = c²) in order to solve for the hypotenuse.
25² + 11² = c²
625 + 121 = c²
746 = c²
√746 = c
Answer:
$6000
Step-by-step explanation:
so she made 72000 in a year, a year as 12 months so to find the monthly rate we just need to divide 72000 by 12 which gives 6000
Answer:
1/2
Step-by-step explanation:
The formula that relates two independent events is provided as below:
P(A) x P(B) = P(A⋂B)
=> P(A) x (1/3) = 1/6
=> P(A) = (1/6) x 3
=> P(A) = 3/6 = 1/2
=> Option D is correct
