Answer:
Using a formula, the standard error is: 0.052
Using bootstrap, the standard error is: 0.050
Comparison:
The calculated standard error using the formula is greater than the standard error using bootstrap
Step-by-step explanation:
Given
Sample A Sample B


Solving (a): Standard error using formula
First, calculate the proportion of A



The proportion of B



The standard error is:







Solving (a): Standard error using bootstrapping.
Following the below steps.
- Open Statkey
- Under Randomization Hypothesis Tests, select Test for Difference in Proportions
- Click on Edit data, enter the appropriate data
- Click on ok to generate samples
- Click on Generate 1000 samples ---- <em>see attachment for the generated data</em>
From the randomization sample, we have:
Sample A Sample B



So, we have:






Answer:
5902
Step-by-step explanation:
Solution: 13% off 45400 is equal to (13 x 13) / 100 = 5902.
0.83 can also be written as 83/100, so the numerator will be 83.
Answer:
25 m = 25 × 100 = 2500 cm
5 ÷ 5 = 1
2500 ÷ 5 = 500
5:2500 ratio simplified is 1:500

Step-by-step explanation:
h(x)=-x-4
but h(x)=4
4=-x-4
x=-4-4
x=-8
