OptionAStep-by-step explanation:95% confidence interval is obtained using the following formulaCOnfidence interval lower bound = mean - critical value * sigma/sq rt nand upper bound = mean + critical value*sigma/sq rt nThus margin of error = critical value*sigma/rt nvaries indirectly as n provided others are remaining the same.Hence lower sample indicates higher margin of errorOut of 4 options given we find that 1 option has maximum margin of error as 21%Hence option. A is most likely coming from a small sample.
To convert a percentage to decimal form, you need to divide the number in the percent by 100. In reality, that just looks like moving the decimal point to the left two places.
83% / 100 = 0.83
83% in decimal form is 0.83.
Hope that helped! =)
Hey there!
“Which expression is equivalent to b + b – 0.56b?”
• “b” or any other letter value is considered an “unknown number” so usually we label it/them as an invisible 1
• COMBINE the LIKE TERMS
(b + b – 0.56b)
(1b + 1b – 0.56b)
1b + 1b = 2b
2b – 0.56b = 1.44b
• Therefore, b + b – 0.56b is equivalent to 2b + 0.56b
Possible answer that you could be looking for: 2b + 0.56b ☑️
Good luck on your assignment and enjoy your day!
