A sample of 100 independent random numbers is taken from this distribution, and its average is used to estimate the mean of the
distribution. What isthe standard error of this estimate?
1 answer:
Answer:
The standard error in estimating the mean = (0.1 × standard deviation of the distribution)
Step-by-step explanation:
The standard error of the mean, for a sample, σₓ is related to the standard deviation, σ, through the relation
σₓ = σ/(√n)
n = sample size = 100
σₓ = σ/(√100)
σₓ = (σ/10) = 0.1σ
Hence, the standard error in estimating the mean = (0.1 × standard deviation of the distribution)

Answer:
30%
Step-by-step explanation:
Percentage loss is calculated as
× 100%
loss = 50000 - 35000 = 15000, thus
percent loss = 
× 100% = 30%
Answer:
Both are irrational.
2^t =38
take the log of each side
log ( 2^t) = log (38)
the exponent gets multiplies
t log (2) = log (38)
divide by log 2
t = log(38)/log (2)
t≈5.2479
Answer:
(cx)2-(dy) 2
Step-by-step explanation:
Formula a2-b2= (a+b) (a-b)
By given formula
(cx)2 - (dy) 2 = (cx+dy) (cx-dy)
