The square root of pie is 1.772
Answer:
here's an equation you could use 600$=23x+12y
Answer:
w = 8
Step-by-step explanation:
11 = w + 3
11 -3 = 8
Answer:
Step-by-step explanation:
calculate x for this equation
f(x) = -5 : -4x +2 = - 5 so : -4x =-7 x = 7/4
f(x) = 2 : -4x +2 = 2 so : -4x =0 x = 0
f(x) =6 : -4x +2 = 6 so : -4x =4 x = -1
f(x) = 18 : -4x +2 = 18 so : -4x =16 x = - 4
the domain is : D = {7/4, 0, -1, -4}
Answer:
Step-by-step explanation:
If repeated sample sizes of large sizes are taken at random, and proportion P is calculated for samples the sample mean will have a normal distribution irrespective of the original distribution.
In other words, the sample proportion will follow a normal distribution with mean = p-hat and std deviation =![\sqrt{\frac{p(1-p)}{n} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%20%7D)
This is a direct corrollary of central limit theorem for sample means.
Hence we have irrespective of sample size, sample proportion will have expected value same as p-hat.
So whether sample size is 500 or 100 the p hat will have the same distribution.
