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:
The probability is
Step-by-step explanation:
From the question we are told that
The proportion that live with their parents is
The sample size is n = 125
Given that there are two possible outcomes and that this outcomes are independent of each other then we can say the Recent census data follows a Binomial distribution
i.e
Now the mean is evaluated as
Generally the proportion that are not staying with parents is
= >
The standard deviation is mathematically evaluated as
Given the n is large then we can use normal approximation to evaluate the probability as follows
Now applying continuity correction
Generally
So for the z - table
