Answer:
3.09
Step-by-step explanation:
The sample proportion can be calculated as phat=x/n
phat=180/590=0.305
The z statistic for proportion can be calculated as
Where p=population proportion=0.25
q=1-p=1-0.25=0.75
n=590
phat=sample proportion=0.305
So, the required z-statistic is
z=3.085
As the rounding of answer to two decimal places is needed, so, the z statistic=3.09.
Answer:
-29
Step-by-step explanation:
-5x^2-6y^2
substitute the x and y values
-5(1)^2-6(2)^2
-5-6*4
-5-24
-29
So I think you’re looking for an outlier not an outliner. An outlier is a piece of data that doesn’t match the trend, like the misfit that doesn’t fit with the rest. For example if I had measurements of 1,2,4,84,3 then 84 would be the outlier. Hope this helps!
