Answer:
y=1/2x+4
Step-by-step explanation:
Slope is 1/2. (m)
Y-intercept is 4 (b)
Slope intercept form is Y=mx+b.
Using the Central Limit Theorem, nothing can be stated about the shape of the sampling distribution for the sample mean, as the sample size is less than 30.
<h3>What does the Central Limit Theorem state?</h3>
It states that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.
In this problem, we have a skewed variable and n < 30, hence nothing can be stated about the shape of the sampling distribution for the sample mean.

Answer:
95% Confidence interval: (0.0415,0.0647)
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 1430
Number of people who responded that astrology was very scientific, x = 76

95% Confidence interval:


Putting the values, we get:

95% confidence interval for the population portion with this belief: (0.0415,0.0647)
Answer:
A.
Step-by-step explanation:
Each mark is worth two. We are inbetween the first mark and 0 on the left. Half of two is one. and since we are in the left quadrant we know it to be negative. Looking down, we see that we are exactly one mark down. As a mark is two, ans that we are going down, this will be a negative two. That leaves us with the answer of (-1, -2)
