Answer:
Step-by-step explanation:
Let X be the length of time between billing dates and checks received and deposited for non-delinquent accounts of an oil company’s monthly credit card customers
X has mean 13.5 and sigma 3 days
Sample size = n =36, x bar = 13
(One tailed test at 0.025 sign. level)
Mean diff = -0.5
Since sigma is known z test can be used
Std error =
Z statistic = -0.5/SE= -0.1
p value = 0.920
p>0.025 hence accept null hypothesis.
My conclusion is there is no statistical evidence that lock box reduced the mean time.
12/5, because 3*4 is 12 and then it 12/5
Ask your teacher for help you didn't give us a lot of details at all . Sorry I could help you .
Answer:
In the given shapes above, we can see that all shapes have four sides.
Above geometrical shapes could be named as Rectangles, parallelogram or quadrilateral.
First two shapes are Rectangles.
Third is a parallelogram.
Fourth and fifth shapes are Rectangles again.
Also we can say all those shapes with four side as quadrilaterals. (Note: A quadrilateral has four sides.)
Below shown shape has only three sides in it.
It is called a triangle when a shape has three sided close figure.
So, we could drag : Not similar - Different Type of shape.
