Answer:
Helena is correct.
Step-by-step explanation:
The slope intersept form of the line is
y = m x + c
where, m is the slope and c is the intersept.
The point slope form of the equation is
So, if there are two points are given, the equation of line is found by the point slope form.
So, Helena is correct.
Answer:
Option C
Step-by-step explanation:
The central Limit Theorem says the sampling distribution of the sample mean is approximately normal under certain conditions
The conditions are
i) the population should be symmetrial. If population is skewed sample size should be sufficiently large atleast 30
ii) Samples should be drawn strictly at random
iii) the sample observations should be independent
Thus we find that option a is not necessary because even for skewed large sample size allows the theorem
Option b is not correct since if population is less than 30, sampling itself is not necessary.
Option d is also wrong since normality is not necessary
Only option C) The sample size must be large (e.g., at least 30) is the necessary condition
This is unorganized you should write it better next time.
The answer is 16.27 rounded to the nearest hundredth
A histogram indicates that a normal distribution could be used as a model for the variable if the histogram is symmetric about its mean.
Given that the <span>relative frequency histogram represents the length of phone calls on george's cell phone during the month of september.
From the histogram, we can see that the histogram is left skewed, hence, the given histogram does not </span><span>indicate that a normal distribution could be used as a model for the variable.
Therefore, the answer is "No, because the histogram does not have the shape of a normal curve.
