The formula for the confidence interval is given by
Sample mean + z*[σ/√n], and
Sample mean - z*[σ/√n]
We have:
Sample mean = 23.95
n = 40
σ = 2.55
z* for 99% confidence = 2.58
Substitute these values into the formula, we have
23.95 + (2.58)(2.55÷√40) = 24.99
23.95 - (2.58)(2.55÷√40) = 22.91
So the lower interval is 22.91 and the highest interval is 24.99
2m = 200cm
4/200
divide both sides by 4:
1/50
Hope this helps ^-^
ASAP Find the minimum, maximum, range, mean, and median for the data set. 12, 13, 13, 17, 18, 19, 27 A. minimum: 12 maximum: 27
True [87]
<span>C.
</span><span>minimum: 12
</span><span>maximum: 27
</span><span>range: 15
mean: 17
median: 17
</span>
Just do 23 minus 6 and that should be the answer because the y-ccordinate is in the same place
