We know that the mathematics test scores are normally distributed with mean μ=82 and standard deviation σ=8.
We know that the central limit theorem states that a selected sample from a normal distribution with mean μ and standard deviation σ is also normally distributed with mean μxbar and standard deviation σxbar.
Also , the sample mean of sampling distribution is μxbar=μ, where μ is population mean.
The standard deviation of sampling distribution is σxbar=σ/√n where n is the sample size and σ is population standard deviation.
The given sample size=n=64.
So, the required standard deviation of sampling distribution is
σxbar=σ/√n
σxbar=8/√64
σxbar=8/8
σxbar=1.
Answer:
Let's say Joe Shmo, who runs a lemonade stand, gets in a situation with some bad guys near the bake sale stand. They say he has to give a third of his lemonade cups to them. If Joe Shmo has six cups of lemonade, how many cups will he have to give them?
Step-by-step explanation:
V=LWH
V=1170
L=?
W=26
H=5
1170=? times 26 times 5
1170=? times 130
divide both sides by 130
9=?
legnth=9inches
