Answer: Option D
Step-by-step explanation:
The equation of a line in the form of "slope-interception" has the following form:
Where m is the slope of the line and b is the interception of the line with the y axis.
In this case we know that the line has a slope of -2. Then .
We also know that the line intercepts the axis y at the point (0, 3) therefore we know that:
.
Finally the equation of the line will be:
If we add 2x on both sides of the equation we get:
The answer is the option D
Answer: Yes, This sample provide evidence that the length of time for baseball games is more than 170 minutes.
Step-by-step explanation:
Since we have given that
Mean length of the games = 179.83
Standard error = 3.75
We need to find the value of P(X>170).
So, it becomes,
Let
Since z is greater than z(critical value).
So,Yes, This sample provide evidence that the length of time for baseball games is more than 170 minutes.
