We need to find 240,000 written as a whole number multiplied by a power of ten.
We need to get rid of the four zeros behind 24 in 240,000.
24 would be our whole number.
We would need to multiply 24 by 10,000 to get 240,000.
10,000 is equal to because there are 4 zeros. Ex. when multiplying 200 by 30, we first multiply 2 * 3 then we add 3 zeros to the end of 6. So for 10*10*10*10, we add 4 zeros to the end of 1 which equals 10,000.
So the answer would be 24 ×
Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The sample size is
The proportion that choose to vaccinate the teen boys is
considering the first statement
The 95% confidence interval is 12% ± the margin of error*standard deviation is false because
The 95% confidence interval is is %12 ± the margin of error
considering the second statement
The confidence interval should not be calculated due to the small sample size is true because from the central limit theorem
np = 64 * 0.12 = 7.68
and this value is less than 10 hence the confidence interval should not be calculated
considering the third statement
A 99% confidence interval will be smaller than the 90% confidence interval is false
This is because as the confidence level increase (for example from 90% to 99%) the margin of error increase which increases the confidence interval
