Answer:
The resulting scatter plot is attached below :
To plot the required scatter plot :
We first take forks on the x - axis and the spoons on the y - axis
Now we arrange the given data in the form of x and y coordinates
Hence, the data becomes :
(2, 10)
(4, 6)
(6, 4)
(8, 1)
(10, 0)
(12, 2)
Now, We plot these points on the graph and get the required scatter plot for the given data.
Answer:
0.15866.
Step-by-step explanation:
We have been given that on average, electricians earn approximately μ= $54,000 per year in the united states. Assume that the distribution for electricians' yearly earnings is normally distributed and that the standard deviation is σ= $12,000. We are asked to find the probability that the sample mean is greater than $66,000.
First of all, we will find the z-score corresponding to 66,000 using z-score formula.
Now, we need to find the probability that z-score is greater than 1 that is .
Upon using formula , we will get:
Upon using normal distribution table, we will get:
Therefore, the probability that the sample mean is greater than $66,000 would be 0.15866 or approximately .
