Answer:
The correct option is c which is if this test was one-tailed instead of two-tailed, you would reject the null.
Step-by-step explanation:
a: This statement cannot be true as the p-value for a 1 tailed test is dependent on the level of significance and other features.
b: This statement cannot be true as there is no valid mathematical correlation between the p-value of the one-tailed test and the current p-value.
c: This statement is true because due to the enhanced level of significance, the null hypothesis will not be rejected.
d: This statement is inverse of statement c which cannot be true.
e: The statement cannot be true as there is no correlation between the current p-value and the p-value of 1 tailed test. The correlation exists between the values of one-tailed and two-tailed p-values.
ANSWER
EXPLANATION
The general term of the arithmetic sequence is
For the first term,we substitute
to get,
Similarly
The sum of the first n-terms is given by the formula,
where l is the last term.
In this case
We substitute these values to get,
We could have also used the formula,
(B) 16.5π
<u>Explanation:</u>
The shape given is a cylinder
The height, h of the cylinder = 4cm
Diameter of the cylinder = 3cm
Radius, r = 1.5 cm
Surface area of cylinder, A = ?
We know:
Surface area of cylinder = 2πrh + 2πr²
Therefore, the surface area would be 16.5π
Answer:
n/3
Step-by-step explanation:
n×by n is=n square.
n/3
Answer:
99 square units
Step-by-step explanation:
We are given;
- a polygon Y whose area is 11 square units
- The scale factor which it was drawn to become polygon Z is 3
We are required to determine the area of polygon Z
We need to know that;
Area scale factor = Square of Linear scale factor
That is;
Area scale factor = 3²
= 9
Hence;
Area of polygon Z = Area of polygon Y × Area scale factor
= 11 square units × 9
= 99 square units
Thus, the area of polygon Z is 99 square units
