Seven hundred and ten thousand two hundred
Answer:
3,4,5 because they only need one dice to be rolled while the rest need to dice to land perfectly
Step-by-step explanation:
Answer: the t-test statistic is - 1.77
Step-by-step explanation:
For the null hypothesis,
H 0: μ = 2600
For the alternative hypothesis,
H a: μ ≠ 2600
This is a two tailed test
Since no population standard deviation is given, the distribution is a student's t.
Since n = 50,
Degrees of freedom, df = n - 1 = 50 - 1 = 49
t = (x - µ)/(s/√n)
Where
x = sample mean = $2450
µ = population mean = $2600
s = samples standard deviation = $600
Therefore,
t = (2450 - 2600)/(600/√50) = - 1.77
Answer:
3/1
Step-by-step explanation:
Answer:
Approximately 63 business students must be randomly selected to estimate the mean monthly earnings of business students at one college
Step-by-step explanation:
confidence interval = 95%
Standard deviation 
= 569
= 1 - 0.95 = .05
= 
= 1.96
We want 95% confidence that the sample mean is within $140 of the population mean
margin of error ( E ) =140
let n be the sample size
margin of error ( E ) = 
squarring both side
n = 63.45
n =63 approximately
