Which course is this for? I feel like I may need a little more information, but the simplest explanation I can give given the question is:
<em>f(x)</em> is the value of a function <em>f</em> evaluated at the value <em>x</em>. The formal definition of a function is a particular set of rules that associates a particular value with another. For an analogy: you can think of <em>f </em>as a machine that takes in an input, transforms it according to a certain set of rules, and produces an output. <em />In this analogy, <em>x</em> would be the input and <em>f(x)</em> would be the output.
Answer:
y = 6.5
Step-by-step explanation:
y = 1.5x + 11
Let x=-3
y = 1.5(-3) +11
= -4.5 +11
6.5
Answer:
For this case we know that : The length of human pregnancy is known to have mean length of 268 days. So then this value need to represent a paramter since is related to all the population and in known
And for this case the value obtained from the sample calculated as:
represent a statisitc (called the sample mean) in order to estimate the population mean.
So then the best option for this case is:
(c) 268 is a parameter and 266 is a statistic
Step-by-step explanation:
By definition a parameter is "any numerical quantity that characterizes a given population or some aspect of it"
By definition a statistic or sample statistic is "any quantity computed from values in a sample" in order to estimate the parameter of interest.
For this case we know that : The length of human pregnancy is known to have mean length of 268 days. So then this value need to represent a paramter since is related to all the population and in known
And for this case the value obtained from the sample calculated as:
represent a statisitc (called the sample mean) in order to estimate the population mean.
So then the best option for this case is:
(c) 268 is a parameter and 266 is a statistic
