Part A: 5 out 25 lobsters have dangerous levels of mercury
Part B: the 95% confidence interval is given by (4.45, 5.65)
since everything is given all I had to do is find the critical value which can be found from the resource packet = 2.064
Using the formula we find 5.05+-2.064*1.45/5 = ( 4.45,5.65)
For this case, we have 95% of confidence that the true mean for the average number of lobsters with dangerous levels of mercury is between 4.45,5.65
Answer:
-2
Step-by-step explanation:
In a linear regression model we have the equation that relates and , where is the estimator of the slope and is the estimator of the Y-intercept. The coefficients and can be estimated with the equations:
. Thus,
55 degrees and 85 degrees as 180-40=140 and so 55 plus 85 equals 140 and 55/5=11 and 85/5=17
Answer:
Uh there's no models
Step-by-step explanation:
Answer:
Step-by-step explanation:
If the extreme ends of a line segment AC are A and C.
If a point B(x, y) divides the segment in the ratio of m : n
Then the coordinates of the point B are,
x =
y =
If the ends of AC are A(-2, 5) and C(2, -5) and a point B divides it in the ratio of m : n = 5 : 1
Therefore, coordinates of this point will be,
x =
=
=
=
y =
=
=
=
Therefore, coordinates of the point B are .
