For this case we have the following equation:
y = 5.50 + 1.91x
Where:
x: dexterity scores
y: productivity scores
For x = 33 we have:
y = 5.50 + 1.91 * (33)
y = 68.53

Based on records kept at a gas station, the distribution of gallons of gas purchased by customers is skewed to the right with me

Sever21 [200]

Answer:

e. The dotplot is approximately normal with mean 10 gallons and standard deviation 0.4 gallon.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size can be approximated to a normal distribution with mean $\mu$ and standard deviation $\frac{\sigma}{\sqrt{n}}$ .

In this problem, we have that:

$\mu = 10, \sigma = 4, n = 100, s = \frac{4}{\sqrt{100}} = 0.4$

So the correct answer is:

e. The dotplot is approximately normal with mean 10 gallons and standard deviation 0.4 gallon.
