Which of the following is not true about the standard error of a statistic?
aniked [119]

Answer:

Only option d is not true

Step-by-step explanation:

Given are four statements about standard errors and we have to find which is not true.

A. The standard error measures, roughly, the average difference between the statistic and the population parameter.

-- True because population parameter is mean and the statistic are the items.  Hence the differences average would be std error.

B. The standard error is the estimated standard deviation of the sampling distribution for the statistic.

-- True the sample statistic follows a distribution with standard error as std deviation

C. The standard error can never be a negative number. -- True because we consider only positive square root of variance as std error

D. The standard error increases as the sample size(s) increases

-- False.  Std error is inversely proportional to square root of n.  So when n  decreases std error increases

What situation would yield a biased sample? Explain.​
viktelen [127]

Can i have the situations?

Someone interviewing the art club at a school to see how many students are going to the art festival.

The art club students are already interested in art, and there is a great chance they will all go, or will all be interested. In order to have an unbiased sample, they could ask every third student that walks through the front doors.

Hope this helped!

Hello!) this is math :( Can you help me please?
Zarrin [17]

The standard form: Ax + By = C.

The point-slope form:

y-y_1=m(x-x_1)

6. We have m =-2 and the point (-7, -10). Substitute:

y-(-10)=-2(x-(-7))\\\\y+10=-2(x+7)\qquad|\text{use distributive property}\\\\y+10=(-2)(x)+(-2)(7)\\\\y+10=-2x-14\qquad|-10\\\\y=-2x-24\qquad|+2x\\\\\boxed{2x+y=-24}

7. We have m = 4 and the point (-3, 0). Substitute:

y-0=4(x-(-3))\\\\y=4(x+3)\qquad|\text{use distributive property}\\\\y=(4)(x)+(4)(3)\\\\y=4x+12\qquad|-4x\\\\-4x+y=12\qquad|\text{change the signs}\\\\\boxed{4x-y=-12}
