Answer:
a. a parameter.
Step-by-step explanation:
A parameter is a property that describes the whole population, while a statistic is a property pertaining to a sample or sub-set of the population.
In this example, the average content of 4 ounces pertains to the 121 bottles sample and thus is a statistic. While the standard deviation of the population is mentioned to be 0.22 ounces, therefore 0.22 is a parameter.
Answer:
(A) The residents of Belmont are more likely to use public transportation because the city has the highest population density.
Step-by-step explanation:
correct on edge
Complex solutions, namely roots with a √(-1) or "i" in it, never come all by their lonesome, because an EVEN root like the square root, can have two roots that will yield the same radicand.
a good example for that will be √(4), well, (2)(2) is 4, so 2 is a root, but (-2)(-2) is also 4, therefore -2 is also a root, so you'd always get a pair of valid roots from an even root, like 2 or 4 or 6 and so on.
therefore, complex solutions or roots are never by their lonesome, their sister the conjugate is always with them, so if there's a root a + bi, her sister a - bi is also coming along too.
if complex solutions come in pairs, well, clearly a cubic equation can't yield 3 only.
Answer:
P=2.326
Step-by-step explanation:
Raw Score (X):=1000
Population Mean (μ):=460
Standard Deviation (σ): =Sqrt(npq)
Where n=1000, p=460/1000=0.46 and q=1-0.46=0.54
Sqrt(npq)=sqrt(460X0.54)=15.7607
Z = (X - μ) / σ
Z = (1000 - 460) / 15.7607
Z = 34.26244
For p-value 0.01
P(x=0.01) = 2.32635
Hence, P=2.326 t 3 decimal places.
