Answer:
The <em>p</em>-value of the test is 0.0512.
Step-by-step explanation:
The <em>p</em>-value of a test is well-defined as per the probability, [under the null hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was the truly observed value of the test statistic.
In this case the output of the t-test_ind method from scipy module is provided as follows:
Output = (-1.99, 0.0512)
The first value within the parentheses is the test statistic value.
So the test statistic value is, -1.99.
And the second value within the parentheses is the <em>p</em>-value of the test.
So the <em>p</em>-value of the test is 0.0512.
So, there are 48 states, let's divide them into 16 groups (because 7+9=16)
48/16=3
so that means there are 16 groups of 3 states.
and those groups are in a ratio of 7:9, seven to 9 groups.
I assume that the 7 refers to the states that border an ocean, then the number of states will be 7*3=21
Answer:
<h2>-5g + 15h - 25 = -5 × (g - h + 5)</h2>
Step-by-step explanation:
-5g = -5 × g
15h = 5 × 3h
-25 = -5 × 5
-5g + 15h - 25 = -5 × g - (-5 × 3h) + (-5 × 5) = -5 × (g - h + 5)
We are given that the hall has a rectangular shape.
Area of rectangle can be calculated using the following rule:
Area of rectangle = length * width
We are also given that:
Area = 7400 square feet
length = 82 feet
Substitute with the givens in the above equation to get the width as follows:
Area of rectangle = length * width
7400 = 82 * width
width = 7400 / 82
width = 90.24390244 feet
To reach the second floor you would look at all ways to enter to building(8) and multiply it by the number of ways to reach the second floor (12).
8 x 12 = 96 possibilities
Think of it in groups.
1st door and 12 possible sets of steps
2nd door and 12 possible sets of steps
3rd door and 12 possible sets of steps
4th door and 12 possible sets of steps
5th door and ..., etc.....
