Answer:
a) Check graph
b)Closer to 0.5
c)Researcher 1 is right.
Step-by-step explanation:
a) Please check attached graph.
b) Please check second graph. It is shown that the value is 0.387 which is closer to 0.5.
c) Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. The researcher 1 is right because there are numerous random variables are exist for this event and normal distribution function is the best function that gives less error for this numerous not-known random variables.
The first bullet is the answer
Answer:
Standard deviation of the binomial distribution
=
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given size 'n' = 800
The population proportion 'p'=0.6
Let 'X' be the random variable of the binomial distribution
a) mean of the binomial distribution = n p = 800 ×0.6
μ = 480
b) variance of the binomial distribution
= n p q
= 800 X 0.6 ×0.4
σ² = 192
Standard deviation of the binomial distribution
σ =
Answer:
f(x) = ($23/week)(x)
Step-by-step explanation:
Hello!
Let's determine the unit rate. I'd suggest finding the cost per week, rather than the weeks covered by a certain amount of money.
Then:
$115
-------- = $23 per week
Then the amount spent as a function of the # of weeks would be:
f(x) = ($23/week)(x)
