Prime factorization is when a number can only be multiplied by 1 so 2 is a prime number because nothing times it self equals 2 or nothing but 1 ×2 is 2 prime factorization is just using prime numbers to break down bigger number like 50 5 and 10 and break down the 10 2 and 5
Answer:
1) Increase the sample size
2) Decrease the confidence level
Step-by-step explanation:
The 95% confidence interval built for a sample size of 1100 adult Americans on how much they worked in previous week is:
42.7 to 44.5
We have to provide 2 recommendations on how to decrease the margin of Error. Margin of error is calculated as:
Here,
is the critical z-value which depends on the confidence level. Higher the confidence level, higher will be the value of critical z and vice versa.
is the population standard deviation, which will be a constant term and n is the sample size. Since n is in the denominator, increasing the value of n will decrease the value of Margin of Error.
Therefore, the 2 recommendations to decrease the Margin of error for the given case are:
- Increase the sample size and make it more than 1100
- Decrease the confidence level and make it lesser than 95%.
The answer is 900
A= L x W
30x30=900
Answer:
True.
Step-by-step explanation:
If we have for a sample of size n=25 a sample variance of 400, the standard error can be written as:
This way of calculating the standard error is the same used for estimating the standard deviation of the sample means for samples of size n=25.
You have two steps to do to complete this problem, combine like terms and simplify. You'll be simplifying (x−4x)+6x^2+8 to −3x+6x^2+8.
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)
