Is √13 greater or less than 3.5
2 answers:
Step-by-step explanation:
Hey, there!!
Because, root 13 means 3.60 also,
So, when you see 3.5 and 3.6 then it's obvious that 3.6 is greator.
Or if you see it in fractional form.
it will be,
18/5 and 7/2.
when we take a like term,
18×2/10 and 7×5/10
They will be ,
36/10 and 35/10.
Which implies 36/10>35/10.
So, the answer is root 13 is not greator than 3.5.

The confidence interval for the mean usage of water is (18.7,20.5).
Given population standard deviation of 2.4, mean of 19.5 gallons per day and confidence interval of 98%.
We have to find the confidence interval for the mean usage of water.
To find out the confidence interval we have to first find margin of error.
μ=19.5
σ=2.4
α=0.98
α/2=0.49
We have to find the z value for the p value 0.49 which is z=2.33
Margin of error=z*μ/
=2.33*19.5/
=0.82
lower level=mean -m
=19.5-0.82
=18.68
after rounding upto 1 decimal
=18.7
upper mean = mean+m
=19.5+0.82
=20.52
Hence the confidence interval for the usage of water is (18.7,20.52).
