Answer:
(iii) The conclusion of a right tail hypothesis test (test of significance) for a population mean at the significance level should always match the conclusion of a two-sided confidence interval for estimating the same population mean at the confidence level 1- (iv) Keeping all other quantities fixed, increasing the significance level will increase the power of the test.
Explanation:
Improving your process decreases the standard deviation and, thus, increases power. Use a higher significance level (also called alpha or α). Using a higher significance level increases the probability that you reject the null hypothesis. ... (Rejecting a null hypothesis that is true is called type I error.)
Increase the power of a hypothesis test
1. Use a larger sample. ...
2. Improve your process. ...
3. Use a higher significance level (also called alpha or α). ...
4. Choose a larger value for Differences. ...
5. Use a directional hypothesis (also cathe called a one-tailed hypothesis).
Answer:
24 and 21 are the two numbers
Step-by-step explanation:
let n represent the unknown number
let n-3 represent the second unknown number
n+n-3 = 45
2n-3=45
2n=45+3
2n=48
n=48/2
n=24
n-3=21
CHECK: 24+21=45
.˙. the first number is 24 and the second number with a difference of 3 is 21

Determine which length form a right triangle
To do this, we make use of Pythagoras theorem where the square of the largest length = the sum of the squares of the other lengths
So:
(1) 12, 35, 37 --- Yes



(2) 16, 30, 34 --- Yes



(3) 18, 24, 42 --- No




(4) 20, 21, 29 -- Yes
