Answer:
Mean $1060
Standard error $34.69
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation, which is also called standard error, .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Population:
Mean $1,060 and standard deviation $190.
Sampling distriution of samples of size 30:
Mean $1060
Standard deviation
Answer:
Step-by-step explanation:
(1) A typical form of equation of a line is:
with, is slope and is y-intercept.
(2) Another straight line has equation in form of:
with is slope and is y-intercept
(3) If these two lines are perpendicular, according to the property of two perpendicular lines on the two-dimensional plane, we have:
x = -1
(4) Transform the given equation of original line into typical form:
<=>
<=>
<=>
=>
=>
=> Option D: is correct (Slope = )
