By rounding each number to the nearest whole number is 23.5
Given,
Estimate 38¼ - 14¾
and, by rounding each number to the nearest whole number.
Now, The solution is :
=38¼ - 14¾ = 153/4 - 59/4
=>
=> 94/4
=> 23.5
Estimation a number to the nearest whole number:
To round a number to the nearest whole number, you have to look at the first digit after the decimal point. If the digit is less than 5 (1, 2 , 3, 4) we don't have to do anything, but if the digit is 5 or greater (5,6,7,8,9) we must round up.
Hence, By rounding each number to the nearest whole number is 23.5

The value of 27 is within 95% confidence interval because it is greater than 26.7 and less than 29.3.
<h3>What is a confidence interval?</h3>In statistics, a confidence interval is a range to estimate for unknown terms.
The most common level is the 95% confidence interval.
It can be calculated by
CI = Mean ± margin of error.
α = 1 - 0.95 = 0.05
α/2 = 0.025
z(0.025) = 1.96
We need to find the
= 0.645
So,
= 1.96 × 0.645
CI =1.26
C.I= 28±1.2652
Upper limit = 28+1.2652
=29.2625
Lower limit =28-1.2652
=26.7348
Hence, The value of 27 is within 95% confidence interval because it is greater than 26.7 and less than 29.3.
